Buying Guide

Choose the right capacity

Match tank gallons or liters to trip length and engine consumption to avoid running out or carrying unnecessary weight

Check compliance and materials

Prefer tanks that list CARB or EPA compliance and durable UV-resistant polyethylene or reinforced plastic for corrosion resistance

Look for compatible fittings and hoses

Confirm hose length, fuel line fittings and connector types are compatible with your outboard and include a secure two-way vent or inline valve

Prioritize leak-proof caps and vents

A vented cap or two-way vent reduces vapor lock risk and built-in pressure relief features increase safety during use

Consider portability and handling

Evaluate weight when full, handle design and footprint (low-profile vs rectangular) for stowage and carrying ease
