04 cummins and the low fuel light is on and guage is on e. It throws a code 462 and 463 if i remember right. I need to know what part it is to replace. Thanks for the help guys

 

Those codes are for the fuel level sender. Check the plug on top of the tank. How full is the tank? This sounds like a great reason to install an airdog system and gut your intank pick up!!

 

its got a predator pump in it. i took the sending unit out yesterday and it looked fine. cleaned all the wires and nothing.

 

That's a bummer Sounds like the sender took a crap! You have two choices Stock unit from a wrecking yard or aftermarket unit but that will have to be compatible with the stock guage. A gutted stock unit is easier! There is someone here selling such a unit you will have to search the forum!
