Query: disappointed

I bought this to replace and repair a bad fuel level sending unit. Once replaced it did not correct the problem. According to the dealer, they sometimes have to replace 3 or 4 before they get one that works. For the normal person that is not possible since you can't return the part once its installed, and who has the money to keep buying the part in hopes of getting one that works. Disappointed.
