Fuel Tanks
The fuel tanks you find on this page are the highest quality plastic fuel tanks available. Unlike metal tanks our fuel tanks will not corrode and they are 30% lighter than a metal tank of the same size. Cross-linked polyethylene is completely resistant to gasoline and diesel fuel.
Most late model automobile manufacturers use plastic fuel tanks because of the corrosion and weight benefits. Each tank is individually tested and certified to US Coast Guard Standards. (CFR 183.580 sub part J) The tanks include fill fittings, vent fittings, level sender, pick-up fittings, return fittings (where applicable) and installation instructions. The location of the fittings cannot be changed; they are part of the mold. All plastic fuel tanks expand about two percent in size after the initial fill with fuel.
You must take the expansion into account when choosing and installing the tank, check out the installation instructions for more information. Proper installation and use will provide you with many years of trouble feel use.

Gas & Diesel Tank Installation
Permanently Installed Fuel Tanks
Ocean Link fuel tanks are designed and manufactured for use with either gasoline or diesel fuel. Proper installation and use will provide years of trouble free service.
All fuel tanks are manufactured using a natural chemically crosslinked polyethylene and tested in accordance with USCG CFR 183.580 Subpart J.
The following instructions for installation and care of Ocean Link fuel tanks should be followed closely. Deviation from restrictions and suggestions will void warranty.
Installation Procedures
- Install the tank in such a manner as to prevent shifting, chafing, bouncing or puncturing. ALL AREAS OF CONTACT WITH THE HULL, STRINGERS, AND HOLDDOWNS SHOULD HAVE NEOPRENE PADDING BETWEEN THE TANK AND CONTACT POINT. Allowances should be made for expansion. ALL TANKS WILL EXPAND 2% IN ALL DIRECTIONS (LENGTH, WIDTH, AND HEIGHT) AFTER EXPOSURE TO FUEL. Typical allowances for a tank measuring 39L X 22 W X 10H would be as follows: 39-3/4L X 22-1/2W X 10-1/4H.
- Deformation of the tank as a result of the mounting procedures will void the warranty. All tanks must be fully supported during mounting. Do not install the tank in a location where it cannot be easily removed (such as removing floors or walls for repair or replacement). DO NOT FOAM THE TANKS IN PLACE!!
- All fuel tanks are UV stabilized and can be safely stored in the sun, however normal precautions should be exercised to prevent dust and other material from getting into the tank. Do not expose the tanks to temperatures greater than 180 degrees F.
- Below-floor tanks fitted with wooden blocks should have neoprene straps around the blocks to allow for expansion. Tanks should be located in the middle of the compartment and aluminum hold down clips should be installed at an angle that allows 3/8″ clearance at the bottom of the tank. Stringers over the top of the tank should have neoprene padding between them and the tank.
- Do not attempt to glue, weld, screw, heat or add fittings or metal fasteners onto the tank. Use only those fittings supplied with the tank. Do not solid plumb the tanks, use flexible lines. Thread sealants may be used if required.
- Do not exceed 20 foot pounds of torque on the 3/8 MPT fitting or more than 35 inch pounds on the sending unit insert. This will give sufficient torque for sealing.
