Fuel problems

Truck won't start, just keeps turning over. If I open the fuel water peacock it releases air like it was pressured up. Than I cycle the key 10-15 times to prime it that truck starts. It has done it to me twice in 1000k. No fuel leaks or codes.

Local ford doesn't know whats wrong, any idea's?

Figured it out. Tank vent was plugged creating negative pressures in the tank. That would cause the lpfp to work harder eventually burning the pumps out.

Plugged with what? You have that much crap in there?

Dust from farm road is my guess. Have to drop tank and see.

We have had 2 11 gas f350 tank vents plug. They are bush trucks though.

I will take a video of my fuel cap being negative pressure to show what I mean.
