OK, one of a few very last things to get for my build is a gas tank. I'm fairly certain I'm going to get a 60's Chevy 20 gal car tank, put it in the rear under the bed and put the filler neck behind a license place flip up holder.
My issue: what sort of sending unit do I use for an under bed tank? What have others done/used to hook up something aftermarket to the stock gas gauge?
