Help for a pathetic newbie

[rkmore]

There is a split in the plastic nipple on the output at the top if the pump.

Will pump some fuel if there is no pressure required so it passed my flow test but as soon as even a little pressure required just squirts back into tank.

Finally resorted to powering the pump directly with my power-probe while I looked into the tank with a flashlight.

What a pain in the rump.

Thanks for all the help! Greatly appreciated.
