Tank vents

The fuel tank vent is a critical component of your fuel system. It allows the tank to breathe, preventing vacuum or overpressure caused by temperature changes or fuel consumption. An efficient vent system prevents tank damage and ensures a constant flow of fuel to the engine. The models you find here are suitable for both gasoline and diesel tanks.

We offer vents in marine-grade stainless steel, resistant to corrosion, and in high-quality plastics. Available in various diameters (from 16 to 20 mm) and fitting types (straight, 90 degrees). Some models feature a vapor lock to prevent fuel spillage in case of heeling or capsize. Always check the diameter of your tank's vent hose before ordering.

A clogged fuel tank vent can cause engine fuel starvation, especially in modern diesel engines. If you notice a drop in performance or difficulty starting, check the vent. Failure to maintain the vent can also cause damage to the tank itself, resulting in fuel leaks.

Basile Workshop Tip

• Annual Inspection: Visually inspect the vent and clean it of any encrustations or dirt.


• Replacement: If the vent is damaged or corroded, replace it immediately with an original replacement model.


• Compatibility: Make sure the new vent is compatible with the type of fuel (gasoline or diesel) and with the existing hose diameter.

Complete your fuel system with our fuel caps and certified fuel hoses.

Frequently Asked Questions

What happens if the fuel tank vent is clogged?

If the vent is clogged, a vacuum is created inside the tank, preventing fuel from flowing properly to the engine. This can cause starting difficulties, power loss, and, in extreme cases, damage to the tank itself.

How do I know if the fuel tank vent is clogged?

The most common symptoms are starting difficulties, engine power loss, strange noises coming from the tank (such as hissing or suction), and, in some cases, deformation of the tank itself. If in doubt, it is advisable to have the fuel system checked by a qualified mechanic.

Are fuel tank vents for gasoline and diesel the same?

Generally, yes, many vents are compatible with both gasoline and diesel. However, it is always a good idea to check the manufacturer's specifications to ensure that the chosen model is suitable for the type of fuel used. Some gasoline-specific models may have different features to manage vapors.

How often should the fuel tank vent be replaced?

There is no standard replacement interval. The life of the vent depends on environmental conditions, fuel quality, and the frequency of boat use. It is advisable to visually inspect the vent at least once a year and replace it if it shows signs of wear, corrosion, or damage.
