Engine/Transmission (1994 - 1998) Oil Pressure Sending Unit Question

[MAleshire]

I'm in the process of ordering and installing an oil pressure sending unit. From the search I did it looks like I need a specialized socket for the job. If the unit is the same size for a '95 as it is for a '98, I've read that the socket is a 32mm deep socket. Other places it is just referred to as a sending unit socket. I need some feedback as to exactly what tool I need to remove the sending unit, and where I can purchase it. I called NAPA, and a couple other auto parts stores and they day they don't have it.



Thanks, Skip

I purchased a sending unit at autozone and socket, about 8 bucks. stormy

You can also use an open-end claw foot wrench with a ratchet and extension, going through the wheel well.

Thanks for the responses. I checked at Cummins ($53. 00), Dealer ($47. 00), and at Wholesalemopar.com ($24. 00+$10. 00 shipping). I didn't call others about part cost yet. I really appreciate the idea of going through the wheel well---I hadn't thought of that.

I used a pair of Channellocks, from underneath.

Are there any opinions about going with a dealer or Cummins sending unit over going with an aftermarket part from a parts store?

My factory sender lasted 270k. The Autozone replacement lasted 200 miles, it's warranty replacement has been fine for 20k.

Geno's has new Cummins units and the brown truck drops it off at your house.

Any auto parts store should have an oil pressure sender socket. Lisle, OEM (Autozone), KD or other brands all make them. It's not Cummins-specific. About $8.



I don't recall the inch equivalent of 32mm, but I've been using the same socket since long before American cars used metric fasteners.



I've also got ~20K on some parts-store brand sender on my Cummins.

just put some pipe dope on the threads and use that pair of channel locks like ewcmr2
