Truck sat a couple years with old gas in it, thats why I replaced the tank, lines, and pump.
I have tried two different pumps now and cannot get fuel to pump. Both pumps appear to be an identical configuration as the old one.
I used a hand held pump to prime the lines, but the fuel pump doesn't seem to engage enough to pump. I tried it out of the truck by hand and it pumps good. Now I am doubting that I have installed it oriented correctly.
The inlet and outlet are marked and corresponding lines connected, and the arm points up.
What would cause the pump not to be actuating properly?
Thanks for any advice.
