Fuel Pump Isuue

[3.8L V-8 eater]

Hi, to all

While I'm waiting for a moderator to give blessing to my new forum account with Racetronix I'll post here....

I put in one of the new 340LPH pumps already assembled on a new sender...After install when turning on the key the pump would not prime...After checking everything out nothing seemed wrong...So i hooked back up the old stock sender and pump layed it the floor and turned the key on and the pump went through it's prime process meaning there are no issues with my hot wire kit, fuel pump relay, wiring with my car etc...

I did however jumper the hot wire relay which put 12 volts to the new pump and the pump kicked on so I know the pump is not bad....Any ideas????

That's what I'm wondering?? Might be the problem seeing that when I did hotwire the relay to make the new pump come on it did not pump fuel through the lines..I figured either the polarity of the pump motor was reversed or I had to purge the lines from too much air???
