Oil Pressure
Last year I purchased a 1966 Ford F100 that I am restoring. Since I was doing some maintenance to the engine I decided to replace the oil pump. Well, now I can't get any oil pressure and it seems that the oil isn't going to the valves as I have the valve covers off and the oil is not getting there. I removed the connector to the mechanical oil pressure gauge and very little oil, if any, comes out of the opening. I decided to reinstall the old pump but it still doesn't work. What can the problem be?

maybe a bad new pump off the shelf. But could be the new pump wasn't primed properly, as well as the replacement of your old pump. Prime whichever one you want with a drill stuck down thru dist. port until you see oil thru rockers. then you're all set

Drill in reverse?
When you used a drill, was it running CCW? I did it once and wasn't
running in reverse and it took a looooong time before getting
flow after I changed directions to the right way. Don't use a cordless
takes even longer.
A friend of mine packs them with vasoline before installing a new one
and claims it always works.

DID you soak the oil pump in oil before installation? I soak it in a can of new oil, and then manually turn the pump while still immersed in the oil to check it before I even install it. It is easier to find out if you have a bad pump before you install it. Also I always replace the pickup Tube with it, as debris can build up in the pickup, and screen starving the pump.

I did not submerge the pump in oil to test it but I did add oil to to top and turned the pump to make sure it went all the way through and it did. I replaced the tube when I installed the new pump so I don't think that is the problem. I guess its just going back to square one and start all over.

Is it a melling M-57?
I guess I didn't notice what motor it is.
Doesn't the pump come apart to access the gears?
Open it up and fill the rotor cavity with vasoline
instant prime.
6 cyl is a m-74
