Oil pressure sending unit

I haven't yet had the opportunity to look and perhaps an answer here will make it a bit easier when I get to replacing the sender.
Where is the oil pressure sending unit located on a Cummins 330 ISC?

On my '98 325 ISC engine in my Alpine the sending unit is on the driver side about halfway near the top of the engine. It has two wires coming from it. When I had to replace mine it was easiest to lift the bed(engine hatch cover) and do it from the inside of the coach. Caution against using any teflon pipe thread material as it needs the metal on metal connection for the ground.

Good luck,

my 1996 cummins 8.3 L sending unit is on th passenger side, mid engine, just above the oil pan lip. easy to change laying on my back. 2 wires one to gage another to warning lite.

Found the sender at the top of the filter head. It has 2 wires available but the sender has only 1 place to connect to.

Unfortunately, it does not match properly to the Teleflex Amega gage I bought to replace the bad OEM unit, which is out of print.

Oh well, back to the drawing board.

Thanks to all who responded.

Don't know if it is different for your model year, but my 02 had the oil pressure sending unit fail under warranty. Cummins had to replace the sender, perform a modification to the wire harness (different number of wires on the sender), and reprogram the engine computer for the new model sender. They had discontinued the old model because of an excessive failure rate.

My query was premature. The wire came off the sending unit.

I had purchased a new gage, only to find it wouldn't work either. Then a new sending unit, only to find the wire had fallen off.

Lesson: Don't jump to conclusions!

For as long as I've been screwing around with these things, you'd think I would have learned something.

Silly me.

There are 2 electrical leads to the oil pressure sending unit, which has only 1 terminal. One (1) lead goes to the oil pressure gage and there is no other place I can find for the 2nd lead to connect to.

Does anyone know where the 2nd lead goes and/or what it is for?
