Okay, my 57 Townsman Station Wagon has been having a fuel issue. I thought it was vapor lock, but then I was thinking it maybe the sending unit. I'm trying to figure out if I will have to drop the gas tank to install a new sending unit. I got the old unit out (and dropped the float in the tank, but used an endoscope and vacuum hose and got it out) without removing the tank, but I want to know what other people have done. The instructions from Danchuk read to remove the tank to install the new unit. To make things a little bit more interesting, my husband and I replaced the original rear with a Currie 9" rear with disc brakes. I'm beginning to wonder, if I have to drop the rear, if maybe I should just replace the gas tank. I'm trying to fix this situation with a non-pain in the butt fix. Any suggestions? Thanks.
