Fuel pump

i'm a bit out of the loop and it's been a few years since i drove the charger on a regular basis but,
if it worked fine with mech. but not elec. your pick up is fine.
if i remember correctly the first time i put an elec. on my charger and whenever i changed the pre-filter i had to leave the hose clamp on the output side a little loose(like a small leak) and run the pump for a few seconds to prime the system to that point.
