I replaced my fuel pump, but it turns out that's not the problem.
My truck wouldn't start and I looked and no gas in the carb thru the sightglass. I pulled the line off the fuel pump and no fuel coming out when I cranked it.
I took the pump apart and nothing's torn, I can't tell if the check valves work ok though.
I had a new pump, it looks like carnival prize quality but whatever. Stuck it in and still no fuel coming out of it.
I think something wrong with line from tank to pump. Otherwise could be with cam actuation, but that seems less likely.
