Passat (B5) :: 2004 - Fuel Nozzle No Longer Cuts Off Automatically After Changing Fuel Pump
Dec 14, 2010
I worked with my buddy troubleshoot and remove a faulty fuel pump. He received it a week or so later and did the install himself. After this, he states that while pumping gas at the gas station the nozzle no longer cuts off automatically when full causing overflow. He says this has happened at different stations and different pumps. I told him to go double check connections and that everything was sealed. I am wondering what could be causing it..

Working on my cousin's 84 F150 351w HO with a Holley 4180 4bbl and auto trans.
I rebuilt the carb because of sticking floats (that and it was filthy and sitting). It fired up and I drove it to my uncle's shop a ways down the road before even adjusting anything. At the shop, it fires right up, idles great and floats and idle mixture screws are now adjusted.
It has a dead spot right off of idle that's been driving me crazy, and stalls in gear if I'm not careful with the pedal.
After reading around here, I looked down the carb to make sure the fuel was squirting as soon as the throttle moved, and noticed there was NO FUEL squirting from the nozzles. So that explains the dead spot...
There was just the needle, then the nozzles, then the screw that went in, same as they came out (only cleaner). Wondering where to go from here to get these working again. Going to pull the nozzles off and see if there's anything obvious going on in there.

My 2013 Prius fills with approx 10.5 Gallons, but around 9 gallons the gas pump nozzle starts to clicks off every 10 cents. Is this normal?

I have a 2000 echo that recently will not allow me to fill the gas tank unless I do it very slowly. Otherwise it continually trips the pump nozzle.

I just picked up a gen II prius last week. it came with 70k miles and almost a full tank, i think 2 'pips' were gone. since I got my car I've driven a total of 135 miles and already my fuel level went down to 2 pips.
I needed to fill up my tank, so on my way home today I went to a gas station filled up with 87 octane fuel. The fuel pump automatically stopped after about 5 gallons. I had less than a quarter tank, therefore my car should not be full with 5 gallons, according to the manual the tank is just shy of 12 gal. I know my prius has the shrinking bladder or whatever since its a g II, but this is a little extreme. According to my car, I've been getting an average of 35 mpg.

5.4 L, Engine runs if primed at the intake. Fuel pump can be heard running but no fuel gets to the engine. Truck is mint and being sold real cheap due to this issue.
Fuel Pump? Filter? Both? I haven't seen the truck, a friend is considering buying it and rolling the dice it is a quick fix. Fuel is in the tank .....

I ran out of gas one day refilled the tank and car still won't start. Took it to an mechanic he got it running ( saying it was the fuse and electrical problem) got it home and the next day it die on me again, so I called him up and he say it the fuel pump, so I got it replaced and it still won't start. So what's the next step on getting my car to start again.

Ok, wifey went to pull out of garage the other day (Tues.) and after putting car in gear, boom it went dead. She started it again and after 2 seconds of sputtering boom dead again. Tried it when I got home and spun over fine, but no fire. screamed fuel pump to me, but I did all the little things first, Fuses #7 and #26 or 28 or something like that, both were good. So I proceeded to check voltage at the pump (It is NOT under the back seat as alot of people told me..) it is under the passengers side mat in the back.
I checked the voltages when my wife was cranking the engine and it was 12.5 volts. When the key is just "on" the volts were 3.5... I went ahead and pulled the pump, not hard - just I had never done it / pumped 12 gallons of gas out.... Tested the pump connected straight to a battery with jumpers (6'+), and nada the pump didn't do any thing. reversed the polarity and it clicked, reversed it again and clicked again, after the 4th time it went to buzzing. I put it back in and nada.
Pump would work sometimes when it was laying on its side. Good enough for me, new pump ordered. New pump installed and cranked it over, nada. Cranked it over again and sputter sputter - vrooooom! Yea! fixed. Well sorta... Read on. Car started up immediately after shutting it off when testing - turned car over to wifey (after flushing brakes and replacing front pads with those niffty green ones...)
OK here is the point to this diatribe: Car's fuel pump isn't firing with the switch "on". it is pumping when the key is switched to "start", and it runs when the car is started. So you have to crank the engine to "prime" the fuel rail. The second time you crank it, it fires right up. Car accelerates well after started but the double cranking cannot be good on the engine's starter. The fuel drain happens sometime after the car has sat for 15+ minutes. If you shut the car off, then wait up to 15 minutes (all I have had time to sit still and check) the car will fire right off. I just don't know what to check now. Could the relay be bad?
I do not hear any humming from the back when the door is opened. What triggers the pump when the door is opened the CCM? It didn't do this before the car quit, always started with a second or two of cranking...

2005 GX470 ... My Issue is that when I pump Gas ONLY in Calif it keeps stopping. I have tried all angles of the pump. I have tried holding back rubber on pump, but that will not work. This is something else. I have been to other states such as TX AZ NM & NV and this problem does not exist.

I have my aux fuel tank pump hooked to upfitter 3. It has worked perfectly until this week. I started to transfer fuel and the aux fuel gauge and fuel pump both quit. The led on upfitter switch 3 still illuminates, but no fuel pump. I found fuse 9 on passengers kick panel is for upfitter 3. The fuse was good. Is there another fuse somewhere for the circuit I've missed? I can trouble shoot the wiring if necessary, but it's tough to do all behind the left side underbed box and not easy to get to. I've missed something simple before I go further????

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?

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?

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.

R's at the dealer today for a faulty fuel float sensor, and they just called to let me know my vehicle has the wrong fuel pump in it. Seems mine has the pump for the Golf/Rabbit with the 4 cylinder engine and they need to keep the car until the part is in.

I recently had my fuel pump replaced in my 2005 GTI ... twice. Both times, the fuel gauge no longer shows a full tank, and doesn't show empty tank correctly. Is there some way to reset the gauge? Is the pump somehow tied to the gauge, or did the mechanics mess the float up when they changed the pump? Sadly I had it repaired somewhere other then the dealer.

Why the frame mounted fuel pump might run after the key is turned off? Then when you turn the key on it may or not run. If it does run it keeps running. shouldn't this shut off after pressurizing the line? is their a pressure switch in the pump that's failing? This has the 3 pump system...
