Buying Guide: Key Considerations For 5 Gallon Generator Fuel Tanks
- Capacity vs. actual volume: Some listings state 5 gallons but the true capacity may be slightly less. Always check the stated capacity and any notes about measurement tolerance.
- Vent valve presence: If your generator setup relies on a vented fuel system, verify whether a vent valve is included or required by your model.
- Mounting compatibility: Compare mounting hole dimensions (hole-to-hole) with your generator’s fuel tank mounting pattern to ensure a proper fit.
- Gauge and hardware: A fuel gauge and grommets are convenient features that help monitor fuel levels and seal integrity.
- Material and durability: Look for high-density polyethylene or metal with a durable finish to withstand outdoor use and transport.
- Included accessories: Some tanks come with petcock, lines, gaskets, and bolts; confirm contents to avoid buying missing parts separately.
- Ventless vs vented: If your system requires venting, choose a vented model or plan for additional vents as needed.
- Fit for your brand: Cross-check listed compatible models to avoid buying a tank that won’t align with your specific generator.
