making sure the fuel system is sealed is critical...
all hoses are sealed and tight
glass fuel is seated and sealed to fuel pump
diapgragm is sealed and BOTH top and bottom surfaces are FLAT (should be soft, pliable, and pull taunt when installed)
wafers/ valves are seating and sealing

you can remove the fuel line in and out and hook a vacuum gauge to the inlet and test for pressure
then hook gauge to the outlet and test for pressure.
cheap and easy thing to do is buy the rebuild kit and rebuild it, is quick and easy...
i too the time to blast the housing and clean up the hardware as well. the new kits have a ethanol compatible diaphragm
