I got a new oil pump from Speedway for my 8CM and was wondering what I need to do to prime it? Thanks in advance!

I've heard this several times. Does anyone out there know why? I would think regular grease (which I've always used) would be better.

Not sure what the Vaseline does different than grease, but that is what you use on automatic transmissions.

Just pouring oil down the oilpressure sender hole will work as good.
Just so the pump is not dry and can make enough suction to pick up oil.
Vaseline will melt and go away almost instantly when oil starts flowing...trying to wash away good quality grease with oil will take a while.
Grease in an automatic gearbox... it will shift like shit for a week until the grease is gone from the valves...been there done that

Thank you Murre; that makes perfect sense. I thought it might have been an old wives tail.

So pour oil down the sender hole is sufficient?

You might want to pick up an old Ford pump, just in case the speedway pump doesn't work.

It seems strange after all these years there are not instructions with an oil pump with large red letters. ATTENTION PUMP INSTALLATION REQUIRES THE PUMP TO BE PACKED WITH VASELINE TO AVOID ENGINE DAMAGE FAILURE TO DO SO WILL VOID PUMP WARRANTY.

Was there a guy on the Ford engine assembly line whose job it was to pack new pumps with vaseline?

Does Speedway sell Melling pumps?

No idea what the factory did, but I would guess that they would pressurize the oil system prior to starting.

I think that may be a reasonable answer^^^^ The vaseline is close to an urban legend
not a true requirement.

while i am not going to brag about being about being a flathead expert like many here with much more experience than me, i have an old trumpet car horn, mid 30s chevy?, and i brazed a pipe thread fitting on the end to make a long sturdy funnel. get every thing ready, then dump most of the 4 quarts to start it, its slow, have something else to do, then remove it and screw in a pressure gauge, spin the motor with the plugs out, and bingo!! oil pressure almost immediately.
