Buying Guide
What should I check before buying a tri fuel kit?
- Engine compatibility: Confirm your engine displacement and model match the kit’s listed range.
- Fuel options: Decide whether you need propane, natural gas, gasoline, or any combination; check the kit’s official fuel support.
- Carburetor modification: Some kits require no carburetor modification; others may need adjustments—verify your preference.
- Gasket and mounting: Look for non-asbestos or OEM-grade gaskets and clear mounting instructions.
- Installation effort: Assess whether your generator requires professional installation or can be done DIY with basic tools.
Practical tips for a smooth setup include verifying fuel pressure requirements, ensuring you have safe gas lines or hoses, and testing the switch’s OFF position to prevent leaks.
