Hello, A common problem- My 1974 Buick Estate Wagon's fuel gauge is stuck on full. In reading the other posts it looks like the ground is bad, or there is a short in the hot wire. In any event, it looks like I need access to the sending unit but given that both the exhaust and tank would have to be dropped I am hoping (probably SOL) that there is an access panel where the jack storage is? If not, has anyone made an access panel? Any and all help is greatly appreciated! Gary
According to my 74 Chassis manual, access is through a filler panel at the forward edge of the quarter panel. Remove the left rear wheel/tire. Pretty Good deal, https://www.ebay.com/itm/1974-Buick...ash=item58aed6efab:g:Ev8AAOSwsWpZ4lwA&vxp=mtr
