Fuel is leaking heavily from somewhere above the starter (onto the starter) and also drains steadily from weep hole in bottom of bell housing (both only when running). Injector lines are tight and dry at pump and block. Watched from top and bottom of truck. Mechanic ran a scope to the injector pump. Checked pump, connections, and "valley" that pump sits in. Cannot find source of leak. Any info would be greatly appreciated.

Mastersounds like you need another set of eyes. it sounds like a return line from the injectors may be leaking. it is those real small hoses that connect them all together.

twalls, May 21, 2012, 04:51RookieThanks. I'll have to see about doing that. My mechanic swears that he checked all injector lines as well as return lines individually (can't confirm that). I guess what makes it believable to me is that most of the fuel is coming from the bell housing weep hole. It seems that a leak from any fuel line should run down the outside of the motor. Do you know of a reason why the majority of the fuel would be going into the bell housing? Then I could point this out to him.
Thanks again,

he will have to pull the upper intake to find it.Roy
