Ok. I have wet 100 shot. Seems after I turn the truck off I loose fuel pressure. Gotta let it prime twice usually to start. My fuel is just connected to the 4an fitting on the rail and I can find absolutely no leaks...it is baffelling me. Any idea?

 

Your fuel noid might be leaking. Disconnect it and put the schrader valve back in the test port and try it again.

 

do you have it setup as a return style? if so u will need a check valve to keep the fuel pressure on the rails

 

If you don't see a leak then it must be leaking internaly. I would guess through your fuel noid. Like said re-install your shrader valve and see if it solves the problem. If so then you need a new fuel noid.

If not then your factory fuel system is probably leaking down.
