I have a 03 Neon that the fuel gauge is only reading about half the tank. It shows empty, but will only take 5-6 gallons. I think its the sending unit, but all the local part stores have is the hole pump assembly. Does anyone know where I can buy just the sending unit.

cant, sorry bro, you have to buy the hole assembly, that is the case with most dodge products from neons to most of the newer ram trucks, they are pricey but unfortunatly you can not buy just the pump.
