Priming the pump consists of dumping some oil into the top of it before installation.... that was all I had to do on mine......
I don't think it is possible to install the pump wrong.....if the driveshaft isn't in the proper spot, the pump simply will not bolt up. Wonder if his pump drive is broken?

I didn't have any problems installing the oil pump. The new pump slid right onto its drive shaft just fine and bolted into place without any problems. It wasnt bent or anything when I installed the new pump.
I think the problem is the new oil pump and the OEM oil pump pick-up tube. I picked up the new pump from Autozone and it is a Melling MI-72. When I threaded the OEM oil pump pick-up tube into the Melling pump and snugged it down. The pick-up tube was rotated about 1.8-1.4 of a turn too far and its intake would not have been submerged, so I had to back it off the 1/8-1/4 of a turn so that it would be submerged. I have a feeling it was intended to be used with the Melling Pick-Up tube which may thread better. Has anyone else experienced this?
I think I'm going to pick up a Melling Pick-up tube and see how that fits this weekend.

i used liquid teflon on the threads just as a lube and sealer.
i put the pump (or tube?) in the vise and threaded in the other, and turned it until tight. it was about a half round out of position so i had to really crank on it to get it back around to the down position.
if its sucking any air, that's a problem.
the only other malfunction would be a bad pump, or something wrong with the shaft, or sometimes the housing can crack when torquing it down, especially if the shaft is misaligned somehow.
if you wanted to diagnose/test the system you can place the pickup in a bucket of oil, and rig up a shaft into the pump (screwdriver or something), and turn it with an electric drill. place a diverter over the pump outlet, cause its coming out...

Ain't that the truth.... primed a 440 with the valve covers off once...... That made a mess in short order.....
