POR-15 Fuel Tank Sealer

POR-15 Fuel Tank Sealer was Formulated for metal and developed as a high-tech sealer that is impervious to all fuels, including the diesel, E10 ethanol, and high alcohol content fuels. This gas tank sealant comes in a silver color and has superior strength with fuel resistance. Also, this gas tank acts as a liner and stops rust, corrosion, and small fuel leaks. Fuel tanks must be free from plastic parts, contamination, and be structurally sound before applying sealer. Gas tanks should be free from loose rust, old sealers, cleaned with POR-15 Cleaner Degreaser, and etched with POR-15 Metal Prep for best adhesion.

Color: Silver

Coverage: 

  • 8 fl oz is enough to coat the inside of a 6 gallon fuel tank
  • 32 fl oz (quart) is enough to coat the inside of a 25 gallon fuel tank

Formerly U.S. Standard Fuel Tank Sealer

- POR-15 Fuel Tank Repair Kit Directions

It is important to understand each product in your repair kit and how it works. Proper chemical interaction is essential for achieving the best possible bond of the sealer to the inside of the tank. Fuel Tank Sealer does not adhere well to plastic. If your fuel tank contains plastic components inside, they should be removed before applying Fuel Tank Sealer.

Please remember these instructions are general guide lines only and cannot and do not cover every application and environment. If you remain unsure as how to proceed, please call toll-free for technical advice at 800-457-6715.
