Marine Fuel Tank Vents

Proper fuel tank ventilation is crucial for the trouble-free operation of your boat's engine. While the motor is running, the quantity of fuel gradually decreases, so the vent system allows for compensating the missing volume with air. Otherwise, a vacuum block may occur, and it would prevent fuel from being pumped from the tank to the engine. Meanwhile, at higher temperatures, the pressure inside the reservoir tends to increase, which can be dangerous in certain conditions. Marine fuel tank vents are crucial parts designed to compensate for the change in the fuel level or the expansion/contraction of hydrocarbons related to temperature alterations.

In gasoline tanks, most of such vents can work as pressure release valves. In our online store, you can find plenty of these parts sourced from leading brands such as Sea Dog, Perko, and Moeller Marine. Available in straight and angled configurations, our vents are made from quality plastic, stainless steel, or zinc-plated alloys resistant to corrosion. Their designs also vary; for instance, for places with a higher risk of damage, you can choose from models with no-protruding caps. Also, pay attention to the vent's size and connection hose diameter.
