Ocean Link Inc's 20-gallon tanks
Ocean Link Inc. offers a 20-gallon tank, the OLT 514, which is rectangular in shape and measures 18.5 x 18 x 16 inches. This roto-molded polyethylene tank is designed for waste and water, and can be customised with fittings to your specifications. It is made to order, and you must order the fittings separately.
This tank is a great option for those in need of a waste or water tank for their marine vessel. Its polyethylene construction ensures durability and resistance to corrosion and pit damage. The rectangular shape also allows for efficient use of space, making it ideal for below-deck installations.

EPA-certified tanks
If you're looking for a 20-gallon marine fuel tank that is EPA-certified, there are a few options available to you. Firstly, Moeller Marine offers a 20-gallon permanent below-deck boat fuel tank that utilises their Above & Beyond innovation. This tank can be securely installed with Moeller's Tank Cradle Hold Down Kit. Additionally, Overton's offers the Moeller Marine 20-gallon fuel tank, which is EPA Low Perm certified and complies with all ABYC, NMMA, and USCG regulations. This tank is constructed from durable marine-grade, rotationally moulded, cross-linked polyethylene plastic, which is corrosion and pit-resistant.
Another option is to consider West Marine, who, in partnership with Moeller, offer a new type of EPA-compliant tank as of 2022. These tanks are required to hold up to 5 psi of pressure caused by ambient temperature changes or heating from the sun. One of the key features is the multi-function tank fill cap, which has a red button in the centre. This button allows users to manually release pressure from the tank before connecting or removing fuel lines, eliminating the need for sprayless fuel line connectors. The cap also includes a valve that completely seals the tank for storage. Additionally, West Marine offers its own 3-gallon EPA Portable Fuel Tank, which is also EPA-compliant and Low Perm certified. This smaller tank features a unique rotational fuel pickup for easy fuel line routing and a 0.5-gallon reserve feature.
While these options are all for smaller-capacity tanks, it is worth noting that EPA certification is crucial for any portable fuel system manufactured for use with outboard motors. Since 2011, the EPA has mandated a near-zero-emissions policy for these fuel systems, which has resulted in some significant changes to tank design. For example, unlike older fuel tanks, EPA-certified tanks do not have manually operated vents that release vapour pressure to the atmosphere. Instead, they have non-venting caps that help to prevent the continuous release of fuel vapours.

Above and below-deck tanks
Moeller Marine offers a 20-gallon permanent below-deck boat fuel tank. The tank utilises Low Permeation Tank Technology and is EPA low perm certified, conforming to all ABYC, NMMA, and USCG regulations. The tank is made from durable marine-grade, rotationally moulded, cross-linked polyethylene plastic that is corrosion and pit-resistant. The fill spouts, withdrawal, and vent fittings are moulded directly into the shell, and the machined aluminium 3/8" withdrawal fitting has 360-degree rotational capability for hook-up convenience. The dimensions of the tank are 11.75"W x 26"L x 16.25"D, and it can be secured with Moeller's Tank Cradle Hold Down Kit (Part No. 300110).
Ocean Link Inc offers a 20-gallon rectangular-shaped fuel tank with dimensions of 26" x 11.75" x 18" (including fittings). The tank is roto-molded and made from seamless crosslink polyethylene. It comes with all the fittings noted on the diagram, including the sender, and is ABYC and NMMA compliant. It is made to order and cannot be returned, so customers are advised to measure carefully before purchase.
Both above and below-deck fuel tanks have advantages and disadvantages. Below-deck tanks are more protected from the elements and potential impact damage, which can reduce the risk of fuel leaks. They also free up space on the deck, which can improve safety and provide more room for other equipment or activities. However, below-deck tanks can be more difficult to access for maintenance and refuelling, and there is a risk of fuel contamination if the tank is not properly sealed. Above-deck tanks are generally easier to install, access, and maintain, and there is less risk of fuel contamination from other liquids in the bilge. However, they take up valuable space on the deck, may be more susceptible to damage, and could potentially be a safety hazard if not properly secured.
When choosing between an above or below-deck fuel tank, boat owners should consider factors such as available space, ease of access, safety, and the overall design of the boat. It is also important to ensure that the fuel tank complies with all relevant regulations and is properly installed and secured to avoid leaks and other issues.
