Fuel pipes, taps and accessories

Fuel fittings are a critical component for your boat's engine fuel supply. A damaged fuel fitting can seriously compromise the fuel system, leading to fuel leaks, power loss, and, in severe cases, engine damage. Choosing a high-quality fitting is therefore essential to ensuring the safety and optimal performance of your boat. Don't risk your next trip with faulty equipment; ensure you have the right boat fuel tank components.

Frequently Asked Questions

Is this fitting compatible with my Yamaha 40hp 4-stroke engine?

To ensure compatibility, verify the internal diameter of your engine's fuel hose and compare it with the fitting's specifications. If you are unsure, provide us with the exact engine model, and we will be happy to help you find the correct fitting.

What is the difference between a brass fitting and a plastic fitting?

Brass fittings offer greater resistance to corrosion, high temperatures, and pressure compared to plastic ones. They are therefore more suitable for heavy-duty applications and larger displacement engines, ensuring greater durability and reliability over time.

How can I prevent fuel leaks from the fittings?

To prevent fuel leaks, use high-quality hose clamps, tighten them correctly, and periodically check the condition of the fittings. Replace the fittings if they show signs of wear, corrosion, or cracks.

What type of fitting is best suited for a flexible fuel hose?

For flexible fuel hoses, it is advisable to use fittings with an olive or ferrule connection, which ensures a secure and uniform seal without damaging the hose. Make sure the fitting is compatible with the internal diameter of the hose.
