Buying Guide: Aluminum Boat Gas Tanks
What capacity should I choose?
Determine your typical voyage length and boat type. Drift and sport boats often perform best with 15-gallon tanks for balance, while smaller craft may favor 6–10 gallon units. For longer, heavier deployments, a larger 19–21 gallon option can reduce refueling stops.
Is aluminum the right choice?
Aluminum tanks offer light weight, corrosion resistance, and easier cleaning. They are a common choice for boats under 30 feet and perform well in environments where fuel exposure or water ingress is a concern.
What about fuel senders and gauges?
0-90 ohm senders are standard for many aftermarket gauges. A built-in gauge helps monitor fuel levels, while a visible gauge on some models improves quick checks during operation.
What fittings and installation considerations are important?
Check your boat’s deck layout for length and width compatibility (some tanks are 30″ long). Confirm filler neck size, vent design, and hose connections (8 AN vs 6 AN) to ensure a leak-free installation. Verify venting and anti-slosh features if you’re running a high-performance setup.
Durability versus cost
All selected tanks use aluminum for durability; some include anti-slosh foam and level sensors. In harsh marine environments, fewer seams and higher-grade aluminum matter for long-term reliability. Consider the need for a cap, venting, and ease of cleaning when comparing options.
Installation tips
- Mount with secure brackets to minimize movement and vibration.
- Use marine-grade sealant at all fittings to prevent leaks.
- Route hoses to avoid heat sources and minimize exposure to debris.
