Drill hole in fuel valve handle and put fttings on valve. Mount the valve onto bracket and then rivet into place on the floor in the tunnel. Worked on the rear fuel lines that go to the tank. Not using the fuel pump so put in an coupling to connect to line that goes to the shut off valve. Time consuming trying to get everything to connect properly. Tubing and fittings have to align just about perfect or the fittings won't even start to thread together.
