Fuel GUSHING down the back of the motor from the valley.

[kitchene]

It started out as a few drops and ended up today leaking probably 3 to 4 GALLONS from a tank. It's running down the back of the motor and from what I could see just from looking at the top of the motor without removing anything looks like it's somewhere in the valley.

Odd thing is, it still runs fine! I'm thinking it's the fuel return but I'm not sure. I'm opening it up in the morning to start digging and I just wanted to know if any of you have seen this and may be able to point me in a more specific direction.

After I get it fixed, I have a hell of a lot of cleaning to do. I had to get it home and it looks like the whole underside of my truck has been armor all'd.

On the bottom of the fuel bowl is a drain , the orings commonly fail . Start there .

there is a metal clamp on the fuel line that rubs and puts a hole in the line that is a commen problem but i dont think it could cause that much fuel loss

Mine did this a couple times in the past. Each time it was coming right out of the fuel bowl. Seems like that funky angled oring that seals the lid to the canister had worked it way crooked and was letting fuel run everywhere between the cap and the can. I finally went to Napa and bought one of their good filters that comes with the new cap and a different style oring and so far it has solved my problem. Good Luck.

does this contain the seals I need?

This is what I was talking about. Just the seal and oring that go on the cap when you replace the filter. From Napa the filter comes with a newer style seal and the cap is actually attached to the filter so you use a new one with each filter change.

Well it's not the fuel bowl. It's back towards the turbo pedestal. I'm thinking it's the fuel return line. Does anyone know where to get a diagram of the fuel system?

metal hangar on a metal fuel line... wore through the passanger side line to the back of the head. is this a return line?

[melmount]

no, the line of the pass side head to the rear by the turbo is the fuel line for the pass side. It goes from the bowl to the rear of the head. Its about a 50 dollar line at the dealer. The fitting on the back of the head is tough to get to. I pulled the intake off to the heads and had the valve cover off when i replaced the last one. The return line is from the bowl to the front of engine drivers side going down. If you are in a pinch some 1/4 inch trans rubber high pressure line and 2 hose clamps on each side will temp repair it.
