i'm having problems with my fuel tank every time i go to put fuel in it, it blows it back out. its like its not releasing the gasses anywhere. its been doing this for a week now then today i looked at my fuel pressue gauge and it was reading 1-2 psi no leaks on the gauge plumming. i'm not sure if the gauge is correct though because i can still get heavy black smoke on acceleration. i think i might have possibly melted a line or something my exhaust came loose under the truck and may have done some damage but the weather has been real crappy and haven't had a chance to look.

 

Sounds like your fuel tank's vent line is clogged.

When are you having that pressure? The 12V trucks run a lot higher pressure than that running, I'd suspect your gauge is bad.

 

it usually runs around 16psi idle and 22psi cruising no its running 2psi running and goes up to 10psi at idle
