Ok I've been having fuel gauge issues. It will read 1/4 at times and full at others and bounce around. It's horribly random. I removed the sender wire and grounded it-gauge went to full. I rmoved it all togehter-gauge went to 1/4. So I put a new end on the wire and its reading full then next time I start it the guage is all over the place. So I was thinking about either replacing the sender and getting a gauge from summit. Question is do they offer an aftermarket gauge to work with this factory gauge or is there another option?
