I just used a marine control cable, or Morse style control cable. They are threaded on each end, then ordered a universal clamp bracket, and the rod end from Summit.
It's the same cable and brackets used for a universal throttle cable setup for a drag car.
I ended up using a small pto cable I bought at the driveline shop.
The 1st one I did I used a marine cable.
I just welded a tab to that bracket that's already mounted on the pump. And got rid of all the solenoid linkage and pushing forward is on, pulled back off.
The cable has enough tension it will stay put in the fuel on or off position.
