I did a search on this and came up with so many different posts , but none of them really talked about the fuel gasuge being pegged. I got a 88 Suburban and the fuel gauge is pegged at about 2-3 o clock position and doesn't move. What do you guys think it might be? gauge,ground, sending unit? if its a ground where abouts should I check? If its the sending unit how can i prove that that is the problem? Thanx guys and sorry for the newb question.
