I have a 2000 GMC Savana conversion passanger van, and the sending unit for the gas tank sticks at 3/4 tank. I didn't know this until the 1st time I ran out of gas. The fuel pump works fine, but I still want to get fixed. The dealer part is about $200 + Labor. Does this unit cross to any other vehicle that I can get? Other than the GMC dealer, I can't find the part, Is there another vehicle that uses the same part? thanks for anyones help.
