Had to get a buddy to come load my truck up yesterday . Lost oil VERY FAST . Its coming fro around the IP / oil sensor location . Obviously its a pressurized leak . Any assumptions ? I did the KDP fix years ago . This leak HAS to be pressurized.

Rusted out stainless braided line [s] that run to the power steering unit or the injection pump are my first guesses.

Tappet cover gasket can make a good leak as well if a chunk of it falls out.

Thanks for the reply. Just found out its the sending unit . Now, do I put another one in it or go to a mechanical set up ?

I'd get a replacement sender from Cummins- yours lasted 21 years, the next one should do too.

Basic problem with mechanical gauges is that you have a much longer and much more exposed oil pressure line that can fail and dump your oil again.
That'S why almost every manufacturer went electric for the gauges a long time ago- cheaper and more reliable.

I`m going to order one today.
