How do I prime a new oil pump? where exactly do I fill it with oil? Do I remove the hex screw at the top or the bottom of the pump and just fill it with oil? White Lithium grease? I searched and couldn't find any info on this subject. Thanks alot in advance

I've never heard of filling a pump with oil to prime it. I believe most people just pull the F/I fuse or disconnect the distributor and crank the engine over a few times to build oil pressure on a new setup or rebuild.

 

Open the backplate and pack the oil pump gears with vaseline. Definitely worth doing as this will help create greater vacuum to pull oil from the pan. You may also want shim the pressure relief valve to increase pressure.

I've heard of that, never tried it (no oil failures on countless engines) but it makes me a little nervous. There's no need to shim the pump, just remove the washer from the relief spring plug.

 

you can use assy lube to coat inside or take allen bolt and fill through there once in car

I like to leave the washer on the plug, I think of it as a crush washer used for sealing. Instead put a washer (shim) under the bolt to compress the spring a bit more. Different ways to skin a cat.

Yeah I see what you're saying... but ITR pumps don't use that washer nor a shim, so I assume it's fine not to. Also there's no pressure on that part of the pump, so it doesn't need a tight seal.
