My 97 Chevy 3500HD has dual tanks, but I cannot get the rear tank to feed into the front. My dealer says it needs a module. About $250 parts & labor. Is there a manual switch that I can install instead, like my old GMC?
www.jcwhitney.com has dual tank manual switches. I would think that the most dollar effective thing to do is buy the OEMpart and install it yourself, vs. installing the manual switch. no telling what you'd have to change to make it work. www.gmpartsdirect.com is reasonable on most things. Dealers over charge as a matter of course.
