Re: Connecting Oil Pressure Line

My newly rebuilt engine is on a stand. I was trying to figure out how to "prelube" pre-oil the engine before startup. I figured that I would tap into one of these ports and run some sort of pressure oiler. What can I use to pressure oil it. ...and can I tab into these ports.
I did exactly that using a Harbor Freight cheapo hand transfer pump. Bought a brass barbed hose adapter and threaded it into the gallery and connected the HF item. I used the black air hose in the photo for the output side as it is designed for pressure and a bit smaller so easier to find an adapter. The pump puts out a fair amount each stroke and pressure depends on how hard you work but it does seem to be enough to get into the needed places. I put a gallon of oil into the engine via the hand pump and then filled the crankcase/filter with another gallon. Also removed the plugs and put a bit of oil directly into the cylinders to wet the rings. Cranked the engine over a bit until there was a bit of pressure from the regular pump before trying to start it.
The engine had been sitting almost 16 years after a rebuild so oil must have done some good because it started right up, nothing protested and engine seems to be running OK.
