My first post!
I recently purchased an 85 K2500. It's setup for dual tanks but only has the driver side tank. The switch is in the cab still but the switching valve, passenger tank, hangers and brackets, and all the lines are missing. I need pictures and details to help me gather the right parts, and also a how to on how to hook everything back up. I know where to buy most of the parts but I can't seem to find the big steel brackets that bolt to the frame. Obviously the hangers are easily found as is the tank and sending unit as well as the valve.
I need to know how the lines are run, how the return line run, and how the crossover line is run.
Thanks guys!

I buy my tank brackets from GM. A chiltons or Haynes manual would be a good start on reinstalling things.

I picked up a Haynes Manual but that thing is about as helpful as a roll of Charmin!
I've kind of figured some of it out. But if anyone can help I'd appreciate it.
There's no evap canister on this truck. I imagine at one point there was one. Also, I'll be replacing the sending unit next month in the one tank I do have. The problem here is that the current one has the three tubes but there's no evap canister and no return line from the edelbrock carb. I was thinking of just ordering one with only two tubes. Any problems this might create? Not that I don't have enough already! Also, how would all this playout when I find and hook up the valve and the passenger side tank?

I don't think your truck had a return line,Just supply and vapor lines. If you are going to put the other tank on you should get a evaporator can and do up right, I might be able to take a pic of the tanks and the lines I have from a 85 chevy(I bought the whole set up from a guy in AL last year).
The book you need is from a company called HELM, they printed all the books for GM. You might find some on e-bay thats where I got mine.Light truck service and the Overhaul manuals,They have everything in there.(Except how to rap a Hayes Manual around a TP roll)

A roll of Charmin is pretty helpful when you are in the crap!

My Bad. If your truck had TBI then you have a return line
Edit;I done some research last night, looking in 74-76 books that I have and there is no info on the dual tanks. Maybe there will be something in the later books 85'
