The 5 Best custom Marine Fuel tanks (2023 reviews)

Attwood has been making great tank for years, thanks to a combination of clever design and high-end materials. It fits the boat better than the first tank. Not only does this work well, it fits in some spaces where others won't. It also states to loosen the cap 1 full turn for 10 seconds to release the pressure build up. The net result is that the tank pressurizes in the summer heat and when it cools down draws in fresh air only to heat up again. The plastic is much thicker than the older ones and they can be vented very easily through the cap. It will flood the engine if pressure builds up.

It has engineered the industry’s only comprehensive epa certified fuel tank-to-engine solution. It is ideal for pontoon boats where more fuel capacity is needed. The Cap has a 5 PSI vent release built in, which means that while the tank will swell up it should never get to a level that's unsafe.

The cap's valve also responds to vacuum so that fuel flow won't get interrupted, and so the tank won't squish when it cools down. It is better than no gauge and there is not enough venting as it builds pressure when setting in the sun.
