Reply to "Oil Pressure Guage"

I'm told that to be sold in the U.S nowadays, a gauge must be within 2% accuracy or better. So any gauge you find at Kragens etc will be more accurate than the stocker. On the back of the block is an electric sender threaded 1/4 SAE pipe. At a hardware store, buy a 1/4" close- nipple and a 1/4" pipe tee, with some teflon pipe tape. Brass is better than iron. Thread the nipple into the block. Thread the tee fitting onto the nipple with one opening pointed up and the second to the side. Thread the electric sender into the side of the tee and the mechanical gauge on the top of the tee. Now your in-dash gauge will tell you the engine's running and the mechanical gauge will tell you how much pressure you have. Within a few minutes, you'll be able to get a rough calibration for driving. FWIW, almost all in-dash gauges read low- some about 50% of reality. There is no known fix for a stock gauge: it's a gauge-sender mismatch.
