I have an old 1978 Perkins 4.108 in my boat. Buying parts is difficult I keep getting the wrong part. I'm looking for a oil pressure sender. i attached two pic's which one the oil sender?

The top pic is the pressure sending unit for the gauge. Replacement is several aftermarket suppliers; Sierra etc.

The bottom is the open/closed pressure safety switch, on your engine probably only wired to the alarm.

If you are looking to get a gauge working, simply puchase a new gauge with its matching sender. The thread size is likely 1/8 NPT. You do not need a Perkins-specific sender for a pressure gauge.
