Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part from 4Boats, manufactured to meet or exceed original equipment standards for portable marine fuel systems.

How do I know if it is compatible?

This cap is designed for 11.3L (3 Gallon) tanks. The most accurate way to verify fitment is to check your tank's depth; this gauge features a rod length of approximately 170mm, designed to fit standard shallow portable tanks.

Does this require batteries for the gauge?

No, this is a fully mechanical system. It utilizes a internal float that rotates a needle via a spiral rod, providing an accurate reading without electrical components.

Note: Ensure the manual vent screw is opened during engine use and closed during transport or storage. Please verify your original part number against the references above before purchasing.
