      Marine Gas Tanks

      For filling and maintaining your boat’s fuel tank systems, turn to the professionals at Wholesale Marine. We carry an extensive line of boat gas tanks from leading manufacturers for both inboard and outboard engine fuel tank systems. Whether you need a fuel filter, a fuel pickup tube, a funnel for pouring, a portable fuel tank, a complete fuel line assembly, hoses and connectors, senders and gauges, a replacement tank, fuel additives, gas caps and deck fills, or just a 14 gallon jerry can by Flo-N-Go, we have you covered. If you are not exactly certain about what you need, speak with our professional staff for solid advice.

      Regardless of its engine, every craft will have a permanent fuel tank below the deck with lines running to either its outboard or inboard engine. Fuel lines require routine maintenance. Wholesale Marine recommends using a fuel line treatment product such as Stabil or StarTron. It’s ironic, but water is the enemy of most boat systems and this is especially true of the fuel system. To maintain your permanent fuel tank (these are also known as boat gas tanks), here are some helpful tips from Wholesale Marine to protect your boat’s entire fuel system from costly repairs:

      1. Water in an engine’s fuel system leads to corrosion and corrosion leads to engine breakdown. Take action quickly when you first locate water in the fuel line or marine gas tank to possibly avoid repair bills altogether.

      2. Water sits under the fuel in a separate layer. If you are offshore and discover water in your fuel and your filter bowl is less than a quarter full of water, drain it and change the filter immediately. Then head in with caution.

      3. Gas inboards require metal filter bowls. Open the valve from underneath, and be sure to reinstall the safety plug in the drain valve

      4. Marine Gas Tanks’ Primary filters (the first filter after the fuel tank) block small amounts of water, but a larger amount might make it through. Be sure to check by dumping fuel from the secondary filter into a bucket and look for any water bubbles.

      5. Flush clean fuel from a jerry can through the engine to the connection at the high-pressure diesel injection pump or the gasoline injector supply rail. Be sure to use a filtered line. Most diesel engines have a manual fuel pump near the secondary filter or on the low-pressure supply pump. On gas engines, turn the ignition on and off to briefly run the fuel pump.

      6. If the motor stalled because of water, loosen diesel injector lines and turn the engine over with the starter until clean fuel runs through it. For gas engines, remove a sensor or plug at the far end of the supply rail and flush it there.

      7. Clean the tank and find the cause. Remove any sludge and inspect for deteriorated fuel fill-cap O-rings or gauge sender gasket seals. Replace as necessary. If your boat’s fuel line runs clean, your engine will as well. Therefore, it is very important that the fuel line be inspected routinely to avoid costly engine repairs caused by a faulty fuel line.
