I have an AC G with a continental N-62 motor. I just restored the motor and fired it up - only to find I have no oil pressure. the oil pump is on the rear upper protion of the motor. It;s not in the pan. Do I have to prime the pump? If so How do I do it? If I do not have to prime it - any ideas what may be wrong
 
Priming is needed. Take the oil pressure gauge fitting out of the block. Use a pump type oil can with straight 40wt oil in it (helps prime). Make a rubber gasket to seal the oil pump tip into the threads, from a piece of small diameter hose. Pump until the system is filled. It could take 5 cans if the oil filter is not precharged. When primed, it will get much harder to pump. Put the gauge line back in and fire it up. It should catch in a few seconds. If the pump is accessible from the outside (cover plate or end cap) remove it and pack the gears with Vaseline and reinstall cover. Doing both is the best. JimN
 
Never saw a centrifugal oil pump before all other pumps are self priming. Most all oil pumps are gear type if the are worn or you have a leak in the pickup line then you need to fix it.

OK tell me I'm crazy then look it up under pump types.
