- Fuel type and filtration: Look for fuel gauge, filters, and corrosion-resistant components to sustain fuel quality.
- Ease of installation: Prefer kits with minimal tools, straightforward mounting, and clear instructions.
- Sealing and safety: Ensure caps, hoses, and fittings provide proper sealing to prevent leaks and vapor emissions.
FAQ
- Do auxiliary fuel tanks fit all generator brands?
Answer: Not universally. Check exact model compatibility and mounting patterns for your generator. - Will a larger capacity tank increase power output?
Answer: No. It increases runtime between refuels, not the generator’s rated power. - Are there safety concerns with external fuel tanks?
Answer: Yes. Ensure proper ventilation, secure mounting, and leak-free fittings to avoid spills. - Is it better to upgrade caps or tanks first?
Answer: It depends on your usage. If refueling frequency is high, a larger tank offers the most runtime gain; if spills are a concern, a better cap and funnel can help. - Can these kits be removed and stored easily?
Answer: Most are designed for semi-permanent attachment, but many can be detached if needed for transport. - Do these kits affect warranty?
Answer: Some manufacturers may have guidelines; check with the generator maker before installing aftermarket fuel systems.
