replaced fuel pump diafram thought i may have been my problem but now fuel seems to be pumping out of the pump from the inlet nipple. The way i know this is because when i start the motor and the pull the hose of that feeds the pump(from tank to pump) i can see it pumping fuel out of it and i can actually feel presure being pumped as aposed to sucking as i would think. am i wrong or should it not be sucking in as to pump fuel up into the carbs right. i dont know where to go with this next its very frusterating.

1. What engine are we playing with? (Hp, year and serial number)

2. Sounds like you go the check valves in the wrong way round...
