Fair enough, sounds like it may be easier to just buy an aftermarket fuel gauge and go for one that comes with a sender. Can anyone suggest a decent one that's not too expensive and the sender unit will fit in a book spec tank ok? I'm thinking that it may look better and be easier to just cut the speedo and warning lights out of the instrument cluster and then fit an aftermarket fuel gauge and rev counter as my sierra instrument cluster had a clock instead of a rev counter
