Does anyone know where to get a good replacement cheap? My oil pressure goes to zero when the engine's fully warmed up and I let it idle, It's done this for several years so I know it's not the motor. NAPA wants 279 bucks.

 

Do not go aftermarket, they do not last. Get it directly from Cummins.

Got mine in Montana - was less than $50. The p/n is: 3923200 (this is for a 98 12V)

 

how is it over 200 at napa i bought one for $50 from them before i went to a mechanical guage

 

I don't know! That's the quote I got Monday from our local NAPA, that's why I posted.

 

your getting ripped off then

 

Looking on the NAPA side on the web, the sender for a 97 is $24.95 and the 98 is $264 (part number ECH 0p6725. Is there a different computer?? they list both 24v and 12v as the same!

 

As I said above get it at Cummins - dont bother with NAPA.

The part number is posted above...

 

thats wierd about the price

 

When you say 98 they may be pricing you one for a 24v, i have noticed when building a buddys 98 12v we had that problem. they kept trying to give us 24v parts

 

ya say its for a 97 rather than a 98 i actiuly still have mine that i took out and it was about $30-40
