New Here - Cummins 330B Oil Pressure.

IF you are asking WHERE the sender is , there is little chance of you effecting the repair yourself.

It will be either electrical the gage , sender or a loose wire or lost ground ,
OR mechanical in the oil pressure regulator , a big $$$ fix.

On a new to you boat first thing I would find out what type diesel (not car) oil is required and change the oil and filter.

I would locate the oil fitting , remove the wire and clean and replace it.

I would then loosten the instrument pannel, R&R & clean the wire ends to the gage AND look for its ground and clean it carefully.

IF that fails I would purchase a MECHANICAL gage and install it where the electric sender was , and see if its an engine pressure problem or just an electric wiring* hassle.

ON most electric gages there is a REQUIREMENT for a good ground to get accurate readings. Depending on the Brand of gages lost or poor ground will lower oil readouts and raise temp readouts.

Good Hunting.
