Can someone tell me what this is leaking?

Hey can anyone tell me what is leaking out of here. I'm covered in diesel. Just changed my lift pump. It went

Anyway I knew I had this problem with the slit in the inspection cover. It drips when running. Missing bolt also. It def isn't a tight seal. But for the life of me can't tell if its diesel/oil/teams fluid.

No big oil leaks or fuel leaks. Besides the lift pump which is fixed. Sometimes this thing blows through oil in the winter. Not sure if that's it or not. No pools or anything. Much appreciated.

Crap I just realized that is a horrible photo. Ill try and grab another when I get home here in a few.

I have no idea what that picture is supposed to be showing. The normal fuel leak is from the bowl drain valve, it runs down the valley and comes out near the transmission inspection cover. Could also be one of the rubber lines to the bowl that has cracked with age.

Enable the flash on the camera. You can just make out that the shot is forward from the right rear, starter, oil pan, part of the tranny; but it appears to be lit from the parking lot lighting, which doesn't provide any clue as to color.

Have you tried getting some of the leaked fluid on a _white_ paper towel? That would clue you in as to its color.

Sorry forgot pic. On it in a few hours. Will post. And put on papertowel.

i just fixed the same problem today, look in the valley behind your fuel filter on top of the engine, if theres fuel in it then take a pressure washer and spray it all off, drive it around the block a few times to evaporate all the water then shut the engine down and look again.... take a inspection mirror and look under the pump, there is a weep hole there. if it isnt dribbleing then check your fuel filter gasket, mine didnt even look like it was leaking. but when i took it off i had found that over time the gasket dried in one small spot and eventually built up enough fuel in the valley to let it drip down the back of the block and into the inspection plate on the trans bell house! good luck my friend!

also you could try putting baby powder in the valley after you washed it, you will see where its leaking from in the white powder!

Awesome advice. Two great ideas. Trying them both as soon as it gets above 32 degrees here in Ohio

actualy dude, i found that i wish id have cleaned my engine off drove it around then didnt check it but parked it real quik, because it leaked more in the mourning at cold start then it did when it was hot, you would probably get a faster and more direct location of fuel if you did that!

It may be a leaky line from the lift pump to the filter housing. I've seen the fuel heaters and the drain valves leak at times also.

Mine is doing the same thing and I've taken the fuel bowl out and cleaned it up checked for leaks and inspected it when the truck was running. After I put that back in and started the truck I could see rivulets of fuel rolling away from the lift pump. I just can't find the exact area of where it is leaking on the pump. What kind of weak points do they have?
