Our kits are specially designed to bolt on carbureted 22R Toyota truck motors, and are designed to use your existing carburetor throttle plates. These are excellent propane conversions - very simple and clean. Most customers report back an increase in power! We test run and tune each and every one of these on our test truck to ensure the best mileage and power. Installation time should take 2 to 5 hours depending on your experience (this includes removal of your existing fuel system). There is little to no fabrication required. Kits include propane carburetor, propane regulator, 12 feet of propane liquid line, air filters, fuel filter, electric solenoid, hose clamps, vapor hose, adapter plate. Additional tank brackets, hose, and tanks can ordered.
