Unhappy Fuel Leak Blues

Ok I'm stumped... occasionally I find 2 or 3 dime to quarter size drops of fuel under my truck towards the radiator end of where she sits at night... never find these for tow consecutive days mind you...

I wipe them up, and then a week might pass and bam, there they are... couple of days, and again...

I can't find any "wet" spots up on the underside of the motor to follow back to a leak source... STYMIED!

This is driving me nuts !

check around the fuel bowl. Is there anything sitting in the engine valley?

Hey Chuck... I've looked high and low... this motor is bone dry... I was wondering if its a pressure release for over crnaking when starting or something... I try to let off of the key when I hear the motor catch, but its the only thing I can think of... do you know if there is an over pressure dump valve on these fuel systems...?

make sure your water release valve on fuel filter is shut completely. it is the yellow piece of plastic on back of fuel filter housing. the drain runs down the engine on the passenger side midway up.

This is the first thought that went through my mind also. It might be juuuuust slightly opened enough to let a couple drops out here and there. If this is it you won't see any wet spots on the motor, the wet spots will be on the drag link and the tracbar I believe.

Not to hijack but on a side note, my drain vavle o-rings are leaking. Does anyone have the part # or know the name of the kit for it?
