      Permanent Fuel Tanks

      For a long time, permanent boat gas tanks were constructed from steel. Over time, those fuel tanks rusted, began to leak or internal rust sediment made its way to the fuel line resulting in clogged fuel filters and carburetors. If your OEM equipment is in need of replacement, contact Wholesale Marine to browse our selection of permanent fuel tanks for sale. We carry a wide selection by RDS and Moeller Marine and our seasoned representatives can guide you to the best option for your boat.

      PLEASE NOTE: If you are looking to replace an old Temp fuel tank, they were acquired by Moeller in 2008, so many of their tanks are still available but now offered under the Moeller name.

      Here are some considerations when replacing your permanent marine fuel tank:

      • What type is it:
        • Belly, below deck, above deck permanent
      • What is its fuel capacity- 12, 18, 24 gallons or more, and the dimensions
        • Length, width, height (where is the fill & withdrawal)
      • What are the material options for your new gas tank:
        • Polyethylene Plastic, or Aluminum

      Deciding between an aluminum vs a plastic tank can be hard and sometimes the answer is ‘what fits in my boat'. Plastic marine fuel tanks are much lighter and less expensive. They are also corrosion resistant, and not susceptible to degradation from ethanol fuels. Aluminum tanks are extremely strong, can offer the added benefit of baffles which prevents fuel sloshing back and forth, and if kept away from corrosion-inducing moisture, should last for years and years.

      The replacing your permanent boat fuel tank is an ideal time to replace old fill and vent hoses, and to install new fuel lines.
