Regulator The regulator is installed under the hood near the front of the engine.  A mounting kit is provided to install the regulator.  The high pressure tubing, and the low pressure hose are connected to the regulator.  Two small coolant hoses are connected to the regulator which are connected to the two coolant hoses which run to the heater core.  This is to keep the regulator warm and from freezing as the regulator gets cold as the pressure of the gas is reduced.
High Pressure Connections The high pressure tubing is routed from the cylinder to the pressure gauge, filling nozzle, and the regulator.  The filling nozzle is located near the regulator and where it is easily connected to the filling station nozzle.  A couple of holes may need to be drilled and the straps included will need to be installed to support the tubing and keep it secured and away from moving parts.  The tubing is connected with high pressure compression fittings.
Mixer Connection The custom sized mixer for your vehicle is installed at the intake of the throttle body.  A hose is connected from the regulator to the  mixer.
Cylinder Valve A cylinder valve is required but sold seperatly as some customers may have their own cylinder and valve.  The cylinder valve is available with 3/4" MPT or 12 UNF.  Our cylinders come with 12 UNF thread and is the type needed if ordering our cylinders. The valve is threaded into the cylinder.  High pressure tubing adaptors are threaded into the outlets.
Cylinder Mounting The cylinder is secured with steel straps which are securely bolted to the vehicle.  Mounting hardware is not included with the purchase of a cylinder.
