Fill hose from truck filler to the gas tank. Check diameters, I had to go to the muffler shop for a steel piece that was the size of the truck metal filler to the tank filler diameter. I purchased the rubber gas hose that fit the gas tank on mine.
On mine, I fab'd up two metal straps to bolt from the frame front of the tank, to the back frame member.
Fuel sending unit and wiring: I used a new M37 sending unit to match the gauge on the dash as far as Ohm resistance.
I had to make a round locking ring for the fuel sending unit to seat and seal into my tank. My tank is the S10 20 gallon. Not sure the opening on the 22 gallon tank.
Fuel lines (rubber 5/16" and 1/4" vent line on the tank.
Don't forget a good ground strap, mine is the woven one.
