After the success of making the Rustang run on the makeshift lawn mower carb intake and carburetor, I had already started planning my next part of the project. There's little things I wanted to do to make the setup more user friendly, as well as be able to test out the performance of this setup. What I planned on was installing an O2 sensor and air/fuel gauge to meter the A/F ratio to be able to see how the mower carb setup is tuned. The next thing is a choke cable, so I can cycle the clutch from inside the cab. The next part is a one gallon fuel can that will be used for testing MPG by seeing how far I can go on one gallon of fuel, pretty simple. An add on that I'll also add that was suggested by another Youtuber was the addition of a fuel bypass and return line in place of the regulator. The mechanical fuel pump would pump most of the pressurized fuel right back to the tank, with some bled off to feed the mower carb. The pressure will be plenty low enough that it won't blow any gaskets or flood out the carb/intake. The first thing that I worked on was installing the choke cable. I found a spot on the firewall that was more to the driver's side to fish the cable through, then flexed the cable around to get it where its pointing straight towards the choke lever on the carb. I used a combination of zip ties to hold the end of the cable on the soup can air cleaner and one of the extra choke cable brackets, held in place with a sheet metal screw to the firewall, to secure the cable fully. The knob end in the cab was secured under the dash at a point where a screw was present that was holding a trim panel piece. I tested out the cable to verify that it would cycle the choke properly, so with that done, I can move on to the fuel system. The next move now is plumbing the gallon fuel can. After disconnecting the main fuel line from the pump, some salvaged metal line was manipulated to connect to the input line on the pump.
