Ford 7.3L Power Stroke (1999-2003) :: Return Line Leaking At Fuel Bowl
Jul 5, 2016
New 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???

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?

My HPOP was leaking so I pulled it our last weekend along with the fuel bowl and put all new seals in. All my previous leaks are sealed but now this stupid fuel bowl is being a major PIA.
The return line coming off the FPR will not stop leaking! It was slowly dripping when I first replaced the bowl and I thought the leak was between the fuel bowl and FPR housing. I ordered new rings and put it back together.... still leaking.
I wrapped a towel around the fuel fitting and realized that is were the leak is actually coming from. I went to the parker store today and got 3 new 60VL5 sleeves. The first one tore while sling over the fuel line (I was using 2cycle oil as lubricate). The second one leaked even worse.
In a desperate attempt to stop the leak, I slid the sleeve onto the fuel line as far back as it would go. I inserted the fuel line into the bowl and then put a thin coat of rtv on the exposed fuel line. I slid the sleeve over the rtv and then put a light coat of the outside of the sleeve. I tightened the nut up and am waiting for things to dry before trying again.
Why is this fitting giving me such a hard time? I've pulled the FPR housing and it is not cracked so I don't know what the deal is.

I am rebuilding the oil cooler and noticed since its removed I have great access to this fuel line pair from fuel bowl to soft lines below. How these disconnect at the soft lines? I happen to have a new set waiting to be installed. Is there a tool required ?

The fuel line on the passenger side under the turbo that leads to the head is leaking looks like from rubbing on the pedestal, anyone ever just cut it and throw in some fuel line and hose clamps?

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'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.

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 have a problem. I have a nylon return fuel line that is SHOOTING out fuel at the quick connect at the fuel pump. See video: [URL] ....
How do I repair? I think the o-rings in the quick connect went bad. I'm thinking to dip the connector in hot water to soften up the nylon, take the old connector off, and put a new connector on. What size connector I need?

Had 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 a 1989 Ford mustang 4 cylinder. The return line tofuel tank is leaking. I am wondering if I need to treat the return line as a "high Pressure line" or if I can repair with regular rubber fuel line and hose clamps.

I 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?

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.

I bought a 2003 F250 7.3 Powerstroke from a buddy of mine with 99,500 miles. It is a former Michigan truck and has some significant rust issues. Oil pan and drivers door will need to be replaced in the not too distant future. And probably bed rails later too.
In any case, I noticed a puddle of tranny fluid on the driveway when I got home today. The passenger side line at the fitting into the bottom of the radiator has corroded through. The fitting into the radiator is pretty rusty, and the line fitting is darn near destroyed. The line itself actually has a hole in it.
I see the same part numbers on different sites with different descriptions. Driver side here, passenger side there, inlet here, outlet there. For the same number.
As near as I can tell, Dorman number 624-059 is the outlet line from the tranny to the passenger side radiator fitting, and should be the part I need. Correct? Dorman 624-058 seems to be the line from the OTA auxiliary cooler and back to the tranny. What I cant find is the line from driver side radiator to the OTA cooler. That fitting is corroded bad too, and I may as well do both of them.

Having trouble figuring out how to remove the rear fuel line from the fuel pump. Doesn't seem to be the type that uses the quick disconnect tool like the front line does.

Someone stopped by the shop today with a problem with the power steering leaking. I checked it out and the return line from the rack to the pump is rusted through and needs to be replaced. The pressure line looks just as bad and will develop a leak soon too, if not replaced. While chatting the customer revealed that while stuck with no power steering, he put motor oil into the reserve tank because that's all he had. It did get him home. My plan is to replace the pressure line first, then cut the return line below the car (where it can be accessed better). Then use my evacuator.
hooked to the return line from the rack. Start the siphoning and fill the reserve tank with the proper fluid to flush everything out. I figured that it would flush the reserve tank, pump, pressure line, and rack. Then replace the return line and top off the tank. Will I have to have the engine running while I flush, and do I need to work the steering wheel left and right too.

Couple of years ago I installed a fuel pressure gauge. I wrapped the fittings with teflon tape. Well within about a year it started leaking. So I shopped around and used Permatex Permashield fuel resistant sealant on the fittings. It says diesel resistant on the package. Couple months later leaking again. So I take it apart again, clean every fitting and follow the instructions to the letter. Well its leaking again. What will resist diesel fuel under 55 psi pressure. All the fittings seem to be pipe thread.

There is fuel leaking from somewhere on the passenger side of the engine.
What things should I be looking for? I'm thinking injector? Is it easy to identify and replace?

Have a 2007 V10 and I want to put in a Magnafine tranny filter. Instructions say to plumb it in to the return line. Which one is this, top or bottom?
