location oil sender for oil gauge

[saltshaker28]

On my yanmar 315 the oil pressure seems low to me it reads 35 lbs at 3200 rpm on a beede gauge does anyone know where the oil sender is located on the motor and what the part # is for the sender ?

The oil sender is located on the threaded manifold block just behind the starter. It is the one closest to the starter. It is likely pointing down on a 90deg fitting and has a single wire, yellow with a black tracer. Not sure on the sender the Beede gauge requires. The port is 1/8" british pipe thread. The senders normally come 1/8"-27 npt. You can go with npt to bpt thread adapters or run a tap through it with a glob of grease to catch any filings. What is the gauge range, 0 to ? I agree oil psi is low. Make sure both of your dipsticks are seated.

the guage goes from 0 to 150 and I will check dipsticks to make sure they are seated
