Dual fuel system wiring

[SPOT MY 6]

I read an old post that said that one of our vendors made a dual fuel system wiring harness. I have a cell to use for race gas which will use it's own pump, and will use the factory tank for pump fuel (which also has its own pump). I need a wiring harness that will switch power from one pump to the other via a switch. I can make a harness and get the relays myself, but would prefer to save time and buy something that is pre-made if it is available.

I do not need any wiring or electonic vavles to swtich the fuel lines. I will be manaully switching the feed and return lines via shut-off valves and y-blocks. I only need the pump wiring.

Thanks for any help or suggestions.

Couldn't you just splice the original fuel pump power wire and then add a 3 position high amp switch so you can switch the power from the stock tank to your cell?
