How Much Does It COST???

The kit does NOT include the tank. Your local CNG mechanic can fill you in on total cost after labor and you can see more information on our FAQ Page. Have your mechanic call us for assistance. Remember, you’ll need to make the kit install compliant with NFPA 52 safety regulations. This requires certain types of CNG high pressure tubing, valves, and compression fittings.
