Hello, what's the best option for replacing the sending unit on my fuel tank. I have the small FASS installed. I just used the included equipment during the install. I figure now would be a good time to handle everything while I'm in there. It seems like I remember a company offering a sending unit with upgraded fuel lines and the like. I can't remember who was doing it. What the general consensus for fixing/upgrading. I'd like my fuel gauge working again.
