Have to get a new fuel level sensor for my 03 3.1 GP. Rock auto has a few of them ranging from $20 for Dorman, Techsmart, and airtex, and up to $90 for the ACDelco/GM brand. Which one do I have to get? I'm sure they will all work the same, but I'd hate to spend $90 plus shipping for the ACdelco one if I don't have to.
