Ford Fuel System :: 1977 F250 - Fuel Leak From Filter Attached To Carburetor

I have a 77 f-250 with a 460 engine and a 4bbl Motorcraft carb and its leaking a substantial amount of fuel out of the newly replaced filter that is attached to the carburetor. The fitting is tight and I even tried buying some small gaskets to seat it, but that didn't work either.

Ford Fuel System :: Possible To Store Carburetor?

Thought I would check and see if it's possible to store a Carburetor. Have a Holley 4160 that I rebuilt and would like to keep as a backup. Thought since the carb has not been installed the gaskets and seals may not be an issue. Other option, swap the Carb on my truck every few months.

Ford Fuel System :: Location Of Ported Carburetor Spacer?

Would like to replace the 2 1/2" aluminum ported 4bbl spacer down to an inch or so. Finding it difficult locating 'ported' aluminum spacers, however, there are several brands of the 'composite' type?

Ford Fuel System :: 1963 - 2100 Carburetor Won't Idle?

I rebuilt a 1963 ford 2B crburetor with manual choke. Put the carburetor on and it runs very rough. Won't go below 800 rpm or it dies and I need to choke it to start. Thought it was a vacumn leak so sprayed WD -40 and no change in idle. So pulled off the carburetor and put on the previous carburetor (with electric choke) and it runs great. I want to use the manual choke to hook up the cable though. I replaced everything in the carb. What do you think it is?

Ford Fuel System :: 1974 F250 - Howling Noise Coming From Carburetor?

I have a 74 f250 with a 67 352 and a 2150 carb. I have noticed that after driving the truck for a while and when its nice and hot, if I shut it off I hear a funny "howling" noise coming from the carb. It does it for about 5 seconds, then goes away. I rebuilt the carb and it still makes the noise. Also when I am driving it, when I have the pedal at a certain point, I can hear a lot of vacuum, I have checked for vacuum leaks, and there are none. The other question I have is, the 352 was out of a standard shift truck, mine is an auto, so I have nowhere to hook my tranny kick down rod to. How I can fix that, besides replacing the carb?

Ford Fuel System :: Installed Holley 4 Barrel Installed But Won't Run - Carburetor?

i just got my edelbrock performer rpm intake and my holley 4 barrel installed but it won't run...the only way i can get it to hit and run at all is to floor it like it's flooded...then it'll run for a second but will never rev up and get going like it should...so i watched some vids on youtube for setting mixture on holley's wich i was pretty sure about anyway...turned the idle mixture screws in to snug and then out 1 and a half turns. is this a symptom of a bad vacuum leak or is it something to do with the carb maybe not enough fuel?

it's a holley 4160...list-6619...which is 600 cfm...it's on a 302 with 3 speed.

Ford Fuel System :: 1979 F150 - Fuel Pump Leaking From Side?

I've had a fuel leak near the pump of my 79 F150 with a 400 for some time. I didn't know exactly where it was coiming from, but fuel was being sprayed on to the oil filter from something near the pump. I assumed it was the steel line, and that it had rusted through or cracked, and was going to replace it when I had a chance. I was poking around today though, and realized that the fuel was not leaking from the line, but from a hole in the side of the mechanical pump.

For someone who knows what these pumps look like, there is a horizontal cylindrical bump out near the top of the pump, on the side of the pump that is away from the engine. The fuel is spraying in a mist out of one side of that. To me, it always seemed to be a screw channel, but I didn't think the pump was 2 halves put together? Need to know more about my pump, what that bumped out section is, or why/how fuel could be spraying out of it.

Ford Fuel System :: Gas Leaking Into Crankcase

I've got a 390 with a 2 barrel intake and a holley model 0-4778 carb...The carb is 6 months old....

Here's the full story...my gas gauge just stopped functioning last week...so I ran out of gas... since then things have been going down hill...

I've searched all the forums and checked the fuel pressure by putting a pressure gauge right before the carb, its reading a steady 6 psi so I don't think the fuel pump is the culprit...

The carb started leaking gas into the crankcase..I checked the float level, cleaned out the needle, and replaced the power valve in the carb...then drained the crap oil/gas and put in a new oil filter and oil...

Then started her up for 2 minutes and she does it again....all kinds of gas in the oil... I've gone thru this about 3 or 4 times now and I've spent so much $$ on oil and oil filters trying to figure this bitch out...

I am now going to tear the entire carb apart and soak it in carb cleaner and if this doesn't work I'm switching over and buying a new Edelbrock...

Ford Fuel System :: 1986 F150 Idling Rough / Leaking Injectors?

I have an 86 F150 that is idling rough. It used to cut out on me until I replaced the fuel pressure regulator. I have read in other posts that the problem for my rough idle could be leaking injectors. When I replaced the regulator I found a bad injector. My question is that if I check my fuel pressure, with the new regulator, would the only way I would lose pressure be that my injectors are leaking?

Ford Fuel System :: 1971 F250 - Gas Leaking - A Lot Of Crank To Start - Rebuild?

I have a 1971 F250 automatic with original stock 360 engine (100k miles). It currently has an Autolite 2100 2bbl carb.

The Autolite is leaking gas out somewhere where I can't see the leak. It takes a lot of cranking for it to start after sitting 10 minutes and my wife won't drive it for fear of being stranded. My attempt at a rebuild must have failed... Also have issues with anti-stall dashpot spring coming off while driving. When the spring and plunger come off I have to hold the gas on a little to keep from stalling while stopped at a light. A couple other parts looked like they needed repair during the rebuilt, but the kit didn't have any replacement (vacuum diaphragm torn). Also, after replacing plugs, plug wires, replacing points with Pertronix Ignitor 2, a new rotor, and distributor cap, it still doesn't hold a steady idle. In fact it is hard to get it down to the spec idle for an automatic without fear of stalling.

To make a long story short, what is a low maintenance 2bbl (new, not rebuilt) replacement carb. The truck needs to be dependably started by my wife for garage sale runs and home depot trips. I could switch to a 4 bbl intake, but would rather wait for another 50k miles and switch the engine over to a rebuild 390 with nicer intake and carb.

Ford Fuel System :: 1987 F150 - Leaking Started From The Rear Tank

1987 f150 302 4spd 4x4. When I bought the truck 4 years and 12K miles ago the orig owner had just installed a new front pump (in tank) and new switch thing on the frame rail. He said shortly after that the rear pump stopped working so he just ran off of the front tank. That's what I've been doing also except as of the last few months it has started to leak from the rear tank (I don't ever put gas in it and was empty when I bought it) and dies periodically from time to time? Where the leak could be coming from. I do suspect the dying has to do with the leak though.

Jeep - Cherokee :: 1998 - Intermittent Cold Starting / Carburetor System With Choke Sticking

I have a 98 Grand Cherokee (V-8) with 127K on it, that sometimes during cold starts acts like an old carburetor system with the choke sticking. It floods, chokes, it sputters, and you have to maintain an RPM of about 2000 to keep it running and get it to snap out of it. A local shop did a tune up on it before this problem started to happen intermittently, aside from this, it seems to run well. I took it back to the shop and they did several diagnostic tests and even got it to do it for them while they had it.

I told them that it seemed like if we released the key from the start position as soon as it began to fire, the problem would happen, if we held it I the start for a bit longer we could usually avoid it. They returned it to me saying that "Yup, if you hold the start position longer it won't happen, and by the way here is a bill for $103." With the recent below zero temps, it's getting worse, almost unavoidable. My wife says it uses a lot of fuel when this is happening but we have not actually tracked the mileage. Other than this it's a great car but I'm ready to drive it off a high mountain cliff.

Ford Fuel System :: Location Of Check Valve That Maintains Fuel Pressure On The System?

I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?

I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.

My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.

So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?

BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).

Ford 6.7L Power Stroke Diesel :: PM-22-A Motorcraft Cetane Booster 5oz Addition?

My dealer tells me 4oz/25 gal is all that I need, and also written right on the bottle. That does NOT seem like much to enhance the lubricity as it will be quite diluted in the fuel. For my tank I figure 5oz or so for a full tank should be about on par, maybe give me a bit extra, with the recommended amount.

There was a comment here that adding a whole bottle isn't necessary and it won't hurt anything either. My question is will there be any benefit for using more than recommended? At what point is it a waste?

Ford Fuel System :: Gas Went Bad - Cleaning Fuel System

I went to move the 2000 yesterday and it will not start because the gas went bad. It has been sitting about 6 months, since it did not snow this past winter. How do I go about cleaning the fuel system? I was thinking suck the gas tank empty with an electric fuel pump, and blowing out the lines with air. Does this sound right?

Ford Fuel System :: E350 - Fuel Tank / Pump Noise After Cutoff

This van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.

I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!

ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?

Ford Fuel System :: 4180c - Fuel Coming Out Of Primary Vent Tube

I have a F-250 4WD with 7.5L which has a MC/Holley 4180c sitting on top. It was getting very poor mpg (like 5-6 miles/gal) and then was getting harder and harder to start. This progressed rather quickly to not starting with fuel coming out of the primary vent tube. I suspect it has to do with the primary float stuck open. I was considering rebuilding the carburetor. Is this over reaction prematurely or is there something like float adjustment that may rectify all of the symptoms described. If a rebuild is in order what is the information I would need to ensure getting the correct rebuild kit. Info that I have so far from research is it is Motorcraft ID #E5HE-9510-MC.

Ford Fuel System :: Stumble And Die After A Short Highway Run At 70 MPH / Fuel Injection Flooding Out?

What would make a FI engine act like its flooding out and dying after a short run on the freeway?

Details:
1994 F-350 351W (just overhauled this winter)
has new TPS, ICM(?).
Dual exhaust dumps right before the tires
new filters in tanks, new fuel filter on frame rail
All fuel lines have been opened and blown out from the tank to the engine compartment fitting near firewall.
Fuel pumps hold good pressure when tested.

Symptoms:
smells like its running rich most all the time
after a short hiway run @ 70MPH it will stumble and die when returning to surface streets.
fuel smell near engine sometimes, but no obvious puddles or leaks anywhere.

May be related?:
When on a longer highway run, I can't use the FWD tank for a long period without the engine stumbling and cutting out or popping at times. But I can swap to the rear tank for a bit then run the FWD tank again for a while. driving up hills it seems to be worse, but I'm in the panhandle of TX right now..good grief!

I am having to drive this truck for work long distances. While I dont expect a vast fuel range, it would be nice if I could go a couple hundred miles on 20 gallons of gas....

Ford Fuel System :: 1991 F250 XLT - Fuel Pump Will Not Stop Running

I just bought another 1991 Ford. This one is a 1/2 ton XLT Lariet with the 302 and for the first time I own a short bed. I also have a 1991 F-250 XLT with a 460 and a 8' bed.

Here is the problem, ( I think) it will not run or at least not for long. The fuel pump, which I am guessing is in the rear tank will not stop running. On the F-250 the pump stops running after a few seconds after I turn on the key.

Where should I start to find out my problem with the fuel system?
