The 6 Best Marine Fuel vent caps (2023 reviews)

The moeller marine fuel vent cap is suitable and reliable and fits well with your daily purpose. This cap fits great on a typical red plastic 6 gal tank that sits in the bottom of a fishing boat. It is designed for a 1/4” fuel line, since more rapid fuel suction like that requires a manually vented cap. It allows proper ventilation and additionally fits different model gas cans. It is perfectly, and seals well.

The pressure built up in these tanks can reach as high as 15 PSI which will force small carburetor engines less than 25HP to flood out when the tank pressure forces fuel into the carburetor. The new one is all plastic (thank you) and will not rust (thank you) - a much better non OEM replacement.

Why We Like This:

Works much better than the non-vented cap
Great product for converting the newer style breathless tanks to allow for pressure escape
Delivers what they promise
