Sierra 24 Gal Topside Tank
Features: Tank Color Red, Tank Capacity 24 gallons, Topside fuel tank. This top-side tank is designed for mounting on the watercraft’s exterior or side rails, keeping fuel off the deck and out of the engine room. Best for boaters needing a dedicated 24-gallon reservoir with straightforward mounting.
Best for: Boats that require a fixed, larger-capacity topside fuel tank with a clear capacity target. Choose this if you want a single, high-volume topside solution that reduces refueling stops on longer trips. Caution: Verify mounting dimensions on your boat to ensure a proper fit with rails or transom mounting points.

Buying Guide
- Fixed vs. portable: Fixed topside tanks, like the Sierra 24 Gal Topside Tank, are ideal for permanent mounting and larger onboard capacity. Portable cans (Scepter, Attwood) offer flexibility for transport and emergency refueling.
- Capacity needs: If you specifically require around 24 gallons, prioritize fixed options close to 24 gallons. For longer trips or very large boats, a combination of fixed high-capacity tanks plus portable backups can be effective.
- Mounting compatibility: Check mounting dimensions, rail configurations, and cap fittings. Some tanks are designed for older boats, while others use standard modern fittings.
- Fuel compatibility and safety: Ensure the tank material and seals are compatible with your fuel type (gasoline, ethanol blends) and comply with EPA/CARB requirements where applicable. Look for UV-stabilized resin for outdoor exposure.
- Vent and vacuum control: Tanks with automatic vacuum valves reduce manual venting and promote steady fuel flow, which is important for consistent engine operation.
- Maintenance and inspection: Consider accessories like gauges, built-in sight gauges, and robust construction that withstands harsh marine environments. Regular inspection of hose connections and fittings is advised.
- Storage and transport: If space is limited, prioritize compact, low-profile designs or collapsible options for easy storage when not in use.
