During the 8ish years of owning this truck I have fixed multiple fuel leaks, both high and low pressure. I'm 99% sure this one is low pressure since pulling the regulator on the cp3 gives me nothing, also the truck starts fine if I let the lift pump run for 6-8 seconds before I crank it. If I DONT let the lift pump run, it is hard to even get it started, it's never acted this bad starting with any of the other leaks before. Weird thing is, no fuel, nowhere... is it possible it could be leaking backing through my Airdog or have anything to do with something inside the fuel tank? Wherever it's bleeding off it's not visible. I already have all new low pressure lines up by the engine and a fairly new filter head. Whatever this leak is it's bad cause it only take 10 minutes of sitting to take forever to start without help from the lift pump running first.
