Yeah it is a stock mech fuel pump, and i know the sock isnt on the pipe in the tank.... I have almost given up... in my mind its either the carb, fuel pump, or the tranny. After its driven for about 10-15 mins... the problem goes away...
thats why i dont see it as being a fuel problem bc if i had bad pressure or if i had something wrong with the carb why would it go away with the drive train warming up....
