POR-15 Fuel Tank Sealer

POR-15 Fuel Tank Sealer was formulated and developed in our own laboratories due to the demand for a high-tech sealer impervious to all fuels, including the new Stage II fuels which have a high alcohol content. This gas tank sealant has superior strength and fuel resistance. Also, this gas tank liner stops rust, corrosion, and small fuel leaks. 

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

It does exactly what it says on the tin.

I had a small fuel leak from the swirl/sump fuel tank on my 79 Jaguar XJs.
I used POR 15 fuel tank sealer, followed the instructions, it worked perfectly.
Thanks.

Service

Very pleased with the service. When I was unable to re-install the lid, you shipped me a replacement.

I used the product to put a light coat on a carburetor brass float that was leaking. Problem solved so far.

- 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.
