I have a 1968 F-250 with a 360 small block. I know the fuel pump works, and there is gas in the lines up until the fuel pump. But the fuel wont go past the fuel pump or through it.
Take the inlet line loose at carb,turn truck over,if you see fuel,something in the carb is stopped up,if you don,t see fuel,check line to pump from carb,if you still don,t have fuel it is the pump.
Or could be filter stopping fuel from getting to pump.
