Engine/Transmission (1998.5 - 2002) Cummins part number?

[DBrickel]

I was just dragged thru this mess. My Cummins dealer said the original sender was dis-continued and he gave me the new one ($30 ). Next day, after reading the instructions, I found out that the sender turned out to be a switch that requires a re-flash of the ECM ($265 ). Oh, by the way, Cummins said they couldn't do the re-flash. . Dodge has to do it. The reflash trashes the gage and turns it into an idot light... . without the light! It would read 55 psi forever. From other threads, I heard that Dodge was promoting this... . not Cummins. It also required a connection of a single wire into some obscure connector that I couldn't find. Cummins said they didn't have any idea where the connector was, but if I wanted to open a ticket, they would look (Still couldn't reflash though). Well, I told them I was mildly dissapointed and they could have their gage (I mean switch back). The parts guy was reluctant to take it back as it was an electrical part. He could discern my sincerity and decided it was best to take the gage back. I went to Dodge and bought their unit (actual sender). It works perfect, but I'm embarrased to say how much I spent ($200). The parts guy saw me grab my chest and decided to knock off 10 percent (cheaper than calling an ambulance). To replace, I layed across the top of the engine and stuck a mirror that reflected from underneath behind the fuel filter. Pretty easy install. Oh, I also had to go to Harbor Freight Tools to get an 1 1/4" deep well socket. . Couldn't find a Craftsman. If you can find a cheaper gage... . good luck. I wished I could have but came up dry.

Every time I start thinking about selling my 95 12 valve, I read threads like this and it takes away any yearning. :-laf

This is the part # I used 4088390NX, I bought it at cummins. Works perfect, and no reflash required. It's been a couple of years now, so I'm not sure if they still carry it.

Thanks, Barney. I got that number off another thread too. I'll call Cummins back & see if I can get it. Hope it works with my model also. I pulled the mechanical gauge out of my old VW GTI yesterday. I know that one reads real pressure & the price was right. :-laf One way or another I'm going to monitor my oil pressure.
