1996 7.3L leaking fuel VERY BADLY.

hey guys i just got my 96 7.3L running and today after i shut it off i smelt alot of diesel i opened the hood and the valley was up to the turbo in diesel fuel now ik this truck has been sitting along time and needs some stuff so, im not worried about fixing it but i was wondering about how to go along doing this?

were could it be leaking?

i have to change the transmission anyways so i might pull the motor and cleana it up a bit also

this is my truck



this is the problem probably leaked 1.5 gallons of fuel in 5 min



Any help would be appreciated and if i take the fuel pump what kind of gasket is under there?

There are a number of threads on how to change that pump. Its critical that once loosened you need to turn the engine over till you see the pump pop up a bit. or you may a lose the piston into the engine. There is an oring at the pump but it could also be the short fuel lines to the bowl. this get brittle over time.

You may also want to tape up those intake plenums, you don't want anything to get in there.

I always break the pump off in the block. Then grab the stub of the pump with vise grips and it pops right out

^^^^^ Fine if you don't mind replacing what might be a perfectly good pump EVERY time you're invesigating a leak. Can get expensive, though....

Leak like this could be anywhere. Fuel bowl, soft lines, banjo bolt, etc. Either of the sensors in the fuel bowl / regulator.

Pull the fuel bowl, replace all of the rubber lines, replace the banjo washers on the fuel pump, I also replaced the fuel pump, had 165,000 miles on it for insurance, took me only a couple of hours not rushing, fuel pump came right out no problems, no more fuel leaks.
