Welp, got the tank cleaned, painted and installed. I examined the sending unit and based on the looks I decided to reuse it. It was clean and the arm moved freely.
Anyway, after busting my lip from a falling tank bracket hanger and mashing my fingers with the ATV jack I got all the installation complete. I decided to move the truck out into the front yard and cleanup around the garage. When I turned on the switch I checked the fuel gauge and it read chock full, off scale full too. The kicker is there isn't a drop of fuel in it!!!!!!
Dang, sounds like the sender is bad to me. Any ideas?
My search skills suck so if anyone has a PN for the 24v fuel tank sender I'd really appreciate it.
