Questions and answers
I need info on conversion 1980 FG15 from gasoline to LPG
To convert a 1980 Mitsubishi FG15N forklift from gasoline to LPG (liquefied petroleum gas), follow these general steps:
1. Install an LPG Conversion Kit: Use a kit compatible with the 4G63 or 4G64 engine (the engines listed for FG15N). The kit typically includes an LPG mixer, regulator (vaporizer), fuel lock-off solenoid, and hoses.
2. Remove or Modify the Carburetor: Depending on the system, either modify the existing carburetor or replace it with an LPG mixer.
3. Install the Vaporizer/Regulator: Mount the vaporizer in a location near the engine and connect it to the engine’s cooling system to prevent freezing. Connect the LPG tank to the vaporizer with a high-pressure hose.
4. Connect the Mixer to the Intake: Fit the mixer between the air filter and intake manifold. Ensure all connections are airtight.
5. Install the LPG Tank: Secure an LPG tank with a proper mounting bracket. Connect the tank to the regulator using approved fittings.
6. Wiring: Wire the fuel lock-off solenoid to the ignition system so that LPG flows only when the engine is on.
7. Adjust and Test: Start the engine and adjust the air-fuel mixture on the regulator for smooth operation. Check for leaks using a gas leak detector.
8. Compliance: Ensure the conversion meets local safety and emissions regulations.
Note: Professional installation is recommended for safety and compliance.
