fuel prime problems So i have a ls 5.3l swap in my 79 chevy, im running a walbro255 fuel pump and a baffled tbi fuel tank.
TO START WITH THIS WALBRO PUMP PUSHING 55 PSI IS Soooooo loud!!
well my real issue is that i pulled up on a snow bank today, and let it run even being on that steep slope. i could hear a change in pump noise, and it ran the pump and sucked the line dry.
so i backed down and tried to reprime but couldnt get the normal high pressure sound im used to hearing, checked my pressure gauge.. 25 psi was all i was getting.
had to limp it home.
let it sit while i was at work, came back and tried again.. same issue.
its done this before but cleared out.
not sure if i need to pull the fuel inlet line and prime? or any ideas whats going on? im always having trouble with this pump
