Picture #1 is what I am selling.  Picture #2 shows how it assembles in air intake system to provide natural gas injection into the engine.  Picture #3 shows the stock intake on a JD 4045 engine.  The system replaces the black hose between the air filter and the intake on the heads.  Included is the replacement hoses, carburetor, lift to raise the air filter housing, 2 psi pressure regulator, solenoid operated valve and an on/off switch.  The engine will still require a minimal amount of diesel to keep the fuel injection system running but it will significantly reduce the diesel usage.  The system came off a JD 4045 irrigation engine.
