I need to replace my sending unit, I have a issue with my gas gauge. It has full and when my tank is empty the gauge reads I have 7/8 of a tank. I can't find a direct replacement other than the Dodge dealership for $400. I'm sure others have had this problem. Are there other replacement units?

Is this for your '99 Cummins with AirDog 150? If so, I suggest this:
Modified liberty fuel module

 

@ Raw, yeah dude that looks like the fix I need! Thank you!

 

No problem at all. If my sending unit every goes, thats the one i'll be putting in.

 

I had to modify my sending unit cause when I disconnected the return line quick disconnect It took the nipple with it. But I had a bunch of fittings and stainless tubing to modifiy a return line.
