Smell diesel and leak under truck

I smell diesel in the cab of the truck (mainly when stopped at light or stop sign etc). I have noticed a leak under the truck almost directly under the oil pan. I thought it was where I changed my fuel filter and pinched the seal. I replaced it with a new on and still have the same problem (maybe not as much). If I leave the truck running it continues to drip. If I turn the truck off it stops shortly thereafter. Any ideas where to start looking? From under the hood I can't see diesel anywhere by just glancing with a flashlight. I've not climbed up and looked real hard. I just was looking for some suggestions to start or any ideas of what this could be.

Have you checked your drain valve - it is the most common source of leaks. Especially if it is pooling up front. Most other leaks run down the back of the valley and drip from the rear of the motor. Here is a source for the replacement o-rings as well as a directional .pdf on how to do the job:

^^ Yep, I agree. The drain line for the fuel bowl comes down on the passenger side of the engine, but higher than the crank pulley. If you're driving and it's leaking, no telling where the fuel will go.

I wished I'd known about that link above. I ended up replacing the whole assembly. $26.79 from http://www.rockauto.com




The o-rings get flattened out sitting in one position for a long time and sooner or later, the fuel starts getting by them.

Did mine some time back. Went through the diesel o-ring site. Very easy to do.

Here's what mine looked like....
