No tubing bender? No problem! Take a short piece of scrap house wiring and remove a 5"-6" long piece of one of the wires (red black or white it doesn't matter) and strip off the insulation so you have only the copper wire. Insert the copper wire all the way thru the brass or aluminum fuel tank tubing and proceed to bend the fuel tubing over a strong curved metal surface such as large socket. The copper wire inside the fuel tubing will prevent the tubing from kinking. Bend it a little at a time and you end up with a nice smooth bend. When you have the tubing bent to the curve and size you want pull the copper wire out of the bent tubing with your pliers and install the tubing into the fuel tank. Save the copper wire for reuse on your next fuel tank assembly.
