I have a1996 f250 7.3 just bought it. My question is. I have duel fuel tanks and when I switch to the front table I have diesel leaking down the bell housing of my trans. Do these have separate fuel line for both tanks or do they conjoin into one. It doesn't leak when I run the rear tank. THOUGHTS PLEASE!!!!!

 

Welcome to the site..

No separate lines,, look into the engine valley, any leaking fuel collects there and migrates down to the rear/right (passenger side) of the engine block where it exits and on down the bellhousing or starter area..

 

I looked there and there was a still puddle of fuel I just don't k ow where it would be leaking from could it be as simple as a fuel filter gasket

 

check your pass side fuel rail under the turbo pedastal
they like to rub togeather under there

 

Also fuel rail plug on the back of the head on passenger side.
