Available Compressed Natural Gas Conversion Kits


-Please hover over a component for a detailed description-

CTS Module – This is a dash-mounted module with a full-color, 4.3-inch touch screen. This provides real-time monitoring of vital engine information through an interactive display. From the touch screen, the driver can easily switch between running on gasoline and running on CNG. Users can display eight engine data parameters at any one time, including RPM, MPH, fuel temperature, CNG fuel level, water temperature, exhaust gas temperature and more. The display includes a light sensitivity meter that automatically adjusts the brightness of the screen to varying ambient light conditions. With the purchase of an optional camera, the included video-in port will also allow the screen to operate as a back-up camera display.

Fuel Gauge – Go Natural kits include the most accurate and easy to read CNG fuel gauges available. Instead of just monitoring tank pressure, these gauges monitor fuel temperature and tank pressure and create an intuitive digital display based on the calculated results. With other systems, the vehicle may fail to start if the gauge indicates the tank is near empty and the temperature drops substantially before the vehicle is needed again. This is because all CNG systems require a minimum pressure and the pressure inside the tank drops with temperature.

High Pressure Hoses – Each hose is constructed with an electrically conductive nylon core that is designed to dissipate static build-up. These hoses also include fiber reinforcement that helps maximize pressure capabilities while remaining flexible. The outside of the hoses are covered with a red polyurethane jacket that provides abrasion resistance and protection from outdoor elements, including ultraviolet light. The manufacturing process includes the installation of permanent crimp fittings. Before being shipped, each hose assembly is conductivity tested and pressure tested to 10,000 PSI. All of Go Natural’s CNG hose assemblies comply with NFPA 52, ANSI/IAS NGV 4.2-1999 and CSA 12.52-M99 certification requirements.

Tank Brackets – Go Natural CNG designs and manufactures all tank brackets to maximize the safety and function of each vehicle. For example, the brackets for the Ford F150 short bed bolts through the stock holes and raises the tank so that multiple pieces of 4 foot wide plywood can slide underneath.

Wiring Harness – Many CNG conversions require installers to splice 24 or more wires. With Go Natural’s kits, only one wire is intercepted. The rest of the wiring plugs into the factory wiring harnesses. This makes our CNG conversions much less likely to malfunction, easier to install, and drastically reduces potential conversion problems.

Fuel Interface Module (FIM) – Go Natural has developed a Patent-Pending Fuel Interface Module (FIM) that reduces potential leak points by more than 50%. The FIM is machined from a block of solid aluminum and combines the coalescing filter, the manual shut off valve and the electronic transducer/gauge into one unit. Combined with Go Natural high pressure CNG hoses, the FIM can reduce vehicle conversion time by up to 6 hours.

Regulator – The regulator reduces the pressure of the CNG from 3,600 psi (found in the tank) to 125 psi (for engine use). The unique design of the Go Natural regulator does not require additional coolant lines to be spliced into the engine coolant. This speeds up installation and eliminates potential engine coolant leaks.

Fuel Rails and Fuel Cups – On bi-fuel conversion kits, Go Natural includes Patent-Pending Fuel Rails and Cups. The bi-fuel rails are custom machined for precision and anodized black for durability. Custom dual-injector fuel cups fit into the custom fuel rails. Each cylinder is fitted with two fuel injectors, one for CNG and one for gasoline. However, the system will only allow the appropriate injector to be fired based on the fuel type chosen. These fuel rails do not require the intake manifold to be modified or machined. This speeds up installation time and eliminates many other potential problems. Plus, this makes it much easier to remove the system if that ever becomes desirable.

Tanks – CNG tanks are available in four types. Type 1 tanks are the heaviest and cheapest and Type 4 tanks are the lightest and most expensive with type 2 and 3 tanks falling somewhere in-between. Tanks are available in a large range of sizes and configurations. It is also possible to install multiple tanks within one vehicle. CNG tank capacity is measured in gas gallon equivalents (GGE). Natural gas remains a gas, even when compressed, so a GGE of CNG is calculated based on it having the equivalent energy content of a gallon of gasoline. The final decision concerning tank choice will depend on factors such as available tank space, weight concerns, budget and desired range. Your Go Natural representative will be happy to discuss your options with you and suggest a package that will meet your needs.
