91 F800 fuel delivery
Well there's the entire fuel system. I replaced all the fuel filters a couple months ago and the truck ran fine. As of right now. After I stop pumping the primer, I hear a high squeal coming from something(most likely a line) but I dont see and drops of fuel -

91 F800 fuel delivery
My ford 7.8l F800 just started shutting off after 15-20 minutes of idling. About a week ago there was a puddle of fuel underneath the fuel/water seperator and thats when this whole issue started. I replaced it, primed it, and the truck started fine but once again it died. Even if I primed it...
