Well yesterday I walked up to my truck and noticed something was leaking under the truck by the trans oil pan and it wasnt trans oil it was diesel, does anybody know where it could possibly be coming from. I want to fix it before it gets worse.
Thanks everybody

Also check the fuel pressure regulator switch. It is a small part. Mine was leaking and following the value cover down to the valley. You need two people, one to apply the step on accelerator to build up the fuel pressure and one to look at the switch. Mine had a crack in it. It would only leak when the pressure was up. Easy fix, expensive parts.
