Buying Guide
What material should you choose?
– Polymer fillers are lightweight and corrosion-resistant but may wear faster in sun-heavy environments. They’re often best for smaller boats or budget-aware installs.
– Stainless steel (316) fillers excel in marine saltwater settings, offering superior durability and longevity. They’re ideal for larger boats or frequent-use scenarios.
What neck size do you need?
How important is a keyless cap?
Keyless designs simplify fueling, reduce cap loss with a retaining chain, and help prevent spills. If you frequently fuel in rough-water conditions or in shared marinas, a keyless option is advantageous.
What about installation considerations?
Check deck thickness, available space around the filler, and whether you need a gasket or a specific mounting arrangement. A reliable rubber gasket and secure chain are essential to prevent leaks and cap loss.
