I've thought I smelt diesel fuel on an off for a while, but never found the source.
Tonight, 17 degrees out I have fuel in the valley and it appears as if the back of the drain valve is wet.
A fuel bowl rebuild is on the short list. Is this typical, the cold weather brings the issue to light?
I've had an engine oil leak for some time. Recently I've had to add about a quart a month. I got some fluorescent dye and added it to the engine oil last time I added a quart. Ran the engine for a few weeks. Then cleaned the engine valley with cleaner and hot water.
Tonight I investigated the top of the engine with a black light. To my surprise, the oil leak is coming from the fuel bowl, right around the drain valve. I can clearly see about a drop every 3 seconds of fluorescent yellow liquid falling into the valley below and yellow all around the valve.
I expected a leak from the HPOP not the fuel bowl. Do I have a bigger problem? Is engine oil getting into the fuel? I plan to replace the seals in the fuel bowl, but not until I know whether I have a larger problem to address.

2003 6.0 no start. turn the key to on and nothing happens. dash lights up as it should but I don't hear the glow plugs cycle and no fuel gets into the upper fuel bowl. turn the key over and nothing happens. No starter click nothing. tried the starter wire to the battery trick and it cranks but does not kick over. checked ficm wires and they are secure as well as the injector wire on the intake manifold. it is the original ficm.
View 6 RepliesNew to me early 99 (4/98) f350 7.3 6 speed. Truck started acting up a few days after I bought it. Return line at fuel bowl was leaking, so started there and found a bad seal on the Fpr (unrelated to the fuel leak due to disentegrated compression sleeve). Fast forward through a bunch of parts swapping that still resulted in miserable lift pump pressure readings, I pull the sending unit out of the tank, expecting to find a plugged screen.
Well, there was in fact a plugged screen... Attached to the bottom of an in-tank pump. How did that get there?!? Everything I've read says there should only be a pickup tube??? Should I get a new sending unit from a junkyard and do the hutch mod or???
Trying to fit my edge fuel pressure sensor. I have a 90* fitting from Diesel O-rings and I can't seem to get the 90 elbow to turn all the way down before it makes contact with the fuel bowl housing. I'm using the drivers side port, should I use the passenger side port? would it have more clearance than the driver side port?
My instinct is to crank it all the way down then tighten the nut, should I just screw it in until it makes contact then tighten the nut? I was worried it wouldn't have enough threads in contact to seal as well as it should and leak.
I want to build a fuel bowl delete/regulated return fuel system for my 2000 f250 . I would like to make a really neat kit and attach all products used so people that want to build their own would have a useful source. I understand that it will probably cost the same but I want to design my own and route it the way I want . I have 3/8 1/2 5/16 and 1/4 stainless tubing as well as a bunch of unions and 90* 45* fittings and a couple tees. What size is the ports for the fuel lines that go into the four corners of the heads . I am a pipe fitter pipe welder by trade so this is basically a mini version of what I do everyday at work. Looking for some size details of the head port sizes so I can get the correct fittings?
View 3 RepliesHad the ole factory fuel separator/bowl drain start leaking on me about a month back. So i ordered and installed a new one, issue fixed. Well last night the fuel leak started again, I looked everywhere and i cant see anywhere else it may be leaking at. I felt the underside of said piece and it didn't feel wet, but the valley is full of fuel.
I got in there and tightened the 4 bolts down some more, they were tight but i got a some turns on em and am hoping i either didn't tighten it down enough or they maybe backed out some. Now just gotta see if that solves the problem, again.... the replacement is a doorman, the o-rings were bigger/thicker than the factory orings on the old part, of which the o-rings were shot.
Like I said once i replaced the part the leak stopped for 3 weeks until last night. If the tightening of the bolts doesn't solve it where should I look next? I have an FRX mod but i checked all that and its dry as a bone around all the fittings by the bowl and the heads. No indications of leaks anywhere around any of the FRX assembly.
I have been smelling fuel on and off for the last few weeks. I thought it was the fuel bowl drain valve so I ordered the kit for the whole fuel bowl from diesel o-rings. I did the rebuild this morning and I don't see any visual leaks. Still smell a strong odor of diesel though. The lower engine cradle is all wet and the valley is still a little wet too. Could I still have a leak and if so where to look? Could it be just wet still from draining the fuel bowl and needs time to go away?
View 14 RepliesI just changed the drain valve on the fuel filter bowl. All went well and no more leak, but now I am getting an "emission system" warning light.
After I replaced the valve, I filled the fuel bowl with diesel fuel. Was there any other priming that needed to be done (if any)? What the emission system warning light may mean?

Should the upper fuel bowl be empty after sitting for 30 minutes?
I believe no. Which would indicate to me a stuck open injector which Iv been suspected of. Iv been trying to track down a miss that I have and Iv been suspicious of a bad injector but ain't been able to pinpoint which one yet.
2004 F550 with a 6.0. I had to clean out my fuel tank, replace the HFCM and filter on top of the engine. When I start the truck it will run for 30 seconds or so, start running rough then die. I opened the cap on the fuel filter housing on top of the engine to make sure the fuel was getting there. I turned the key on and the fuel bowl quickly filled up.
After a short time however, the fuel drained out. To where I do not know. I don't think this is normal as every time I've changed the upper filter on a 6.0 it is always full of fuel. Why could this one be draining out and could that be the issue why the truck dies after starting and running for a short period of time. I changed the o-ring on the cap and the new HFCM was purchased from Ford.
I have an isspro gauge and did the blue spring about 5 years ago. Since then my fuel pressure is in the 65psi range.
Last week it dropped to 50-55 normal driving and I figured the HFCM was on it's way out (195,000 miles). Replaced the HFCM and the pressure was a bit higher, but not back to it's usual range. Then pulling the boat home from the lake a couple days ago, I saw it at 45psi. On a couple hills it went as low as 40 psi, so I was getting gripped...coasting downhill it only went back up to 50 psi and no higher. Got 'er home and currently not driving it.
In garage with Key On Engine Off, during injector buzz, I can hear a hissing/air noise at the upper filter bowl. Also, the bowl drains empty once the pump cuts off and the sound of air stops too.
I am hoping it's a regulator issue, but I don't know if they are known to wear out or go bad, or if something else in the upper filter housing went bad. So I ordered a new upper fuel filter housing which also has the oil filter tower attached and I'm assuming that these new units would come with the blue spring upgrade already done.
I can check for codes tomorrow when I bring my computer home from work, so I haven't checked for codes yet. I pick up the new filter housing tomorrow and will periodically check back here during the day tomorrow.
Also, while I'm at it: the new HFCM doesn't have the heater. Can I just leave the old connector from the harness un-connected to anything?
I have noticed a refrigerant oil smell coming out of the A/C vents when I first start my truck with the a/c on.. smells like the PAG oil in the A/C system.. I got under the truck and stuck my finger in the condensate drain and it's oily, and has the same smell.. the A/C is still blowing cold, but the smell is getting worse..
View 10 RepliesAfter fixing my fuel pressure regulator leak, I found the fuel soaked track bar bushing coming apart.
The whole thing is available, but do the bushings are available? I've seen some poly kits for the '04 and older but nothing for the newer trucks. It's not a budget breaker either way, but it seem silly to throw away the giant bar because the bushing is shot.
If these will fit? 99-04 F250 Track Bar Bushings Red....
I've got a leak that appears to be coming from the secondary fuel filter housing (the one in the engine compartment)... It's not coming from the filter, but from the side, where there are 4 allen bolts that attach a fitting to the side of the housing...Can I change out the gasket for that piece? I've already tightened the bolts, but the leak persists.
View 14 RepliesI've experienced a fuel leak, I've checked all over, and the only thing I've came up with so far, was maybe its coming from the banjo bolt going into the front of the driver side head.. I cant really get to it good enough to tell though..
View 6 RepliesI'm checking all places to look for a fuel leak. I park on a concrete slab, with no drips.
I have already mopped up as much fluid from the valley from recently having all of the injectors replaced. I still need to clean it further with simple green, and stuff white paper towel in the valley so I can really know if there is a leak.
3 years ago I replaced the water drain valve o rings, but I suppose they could have gone bad again.
I have a 2003 F350 6.0 Lariat Crew Cab long bed. I have had a fuel leak issues for about 2 weeks now. The first fuel leak issue was from the blue spring regulator. I was going to change the part this friday. Well i just drove to get food and back to the house was only gone for 15 to 20 minutes amd never cut the truck off. So i got back home and parked the truck and i cut it off and got out and all of a sudden i here this noise like you hear when a tire has a hole in it and its leaking air out then all of a sudden I hear fuel just pouring out and smoke coming out of the hood. Its night time here where i live so i cant get up under the truck to see exactly what is going on. But I did check to see if it was the regulator housing and it didn't look like any of the fuel lines was leaking that i could see.
View 4 RepliesBrothers of fte. I reach out. Tonight it appears I had a fuel bomb under the hood.
I've been chasing a fuel leak. Replaced fuel drain orings but one screw seemed to not snug up. Also the plastic was so brittle I couldn't replace the inner oring. Installed new valve worked great. A week later noticed new slow drips. Replaced fuel filter. Again good for two weeks.
Tonight pulled into the driveway hopped out immediately smelled diesel. Steaming from under hood. Popped the hood and everything was wet. Moved her to the street and it clattered like I was running out of fuel. Still half a tank though. Hosed of the drive. Popped hood again fired it up easily. Started fine. No noticeable leak. But everything is wet from fuel. Insulation on hood was saturated. When I open the hood fuel ran out of the insulation into the air intake. Batteries were wet!
Alright what gives? Do I have to be under load to see this leak?

the past few days I started smelling diesel fumes in the cab of my truck with bent on and also at the front of the truck when installing new bumper and winch. It's not real strong in the cab but pretty stout at the bumper. I have poped the hood and made a quick visual inspection and from underneath the only evidence of any leak is some power steering fluid which is a different issue (I think)
a week or 2 ago I was cleaning the Ex and noticed 2 or 3 drops of red fluid on the concrete under the Ex I crawled under and looked up and the steering knuckle was pretty wet. Popes the hood and took a look from the top and the power steering pump was sticky and dirty but the only fluid was on the top of the cap.. I'm not real familiar with the set up on the Ex but I have heard the PS support the break booster. From visual inspection it seems as though the fluid is coming they the small (vent?) hole on the cap. What I can/need to do to stop this?
Diesel smell in cab. 2000 F350 7.3 158K on the clock. Just noticed it 3 days ago. Been meaning to address the passenger side fuel line clamp issue. Learned about that one here. Gonna tear the stuff out to get at that one Tuesday. Replacing the clamp. Hope the fuel line is not already compromised.
