As such, I will retain the oil system but am replacing the OEM digital gauge (which is bad anyway) with a pair of conventional marine analog gauges. One is a multi-gauge that indicates oil pressure and I would like to install a sensor and do that. As there is a feed hose, a return hose, and that short L shaped hose from the block to the lower rear of the carb, if I were to find a workable pressure sensor, where would be the best place to install it and, as such, what would a normal pressure reading be?
