What You'll Learn

A pint of POR-15 Fuel Tank Sealer is enough for a 12-gallon tank
A pint of POR-15 Fuel Tank Sealer is enough to seal a 12-gallon tank. This product is designed to seal pinholes and seams and prevent rust, corrosion, and leaks. It is also non-porous and flexible.
One user who sealed a 12-gallon tank with a pint of POR-15 Fuel Tank Sealer had about a third of the pint left over. Another user who sealed a tank of slightly under 12 gallons ended up using only about 25% of the pint can. This user also mentioned that they tend to overdo things and couldn't get all of the excess sealer out of the tank due to the lip on the drain plug opening and the filler tube hole indent.
According to POR-15, a pint will treat up to a 12-gallon tank, but 2 pints are recommended for most car tanks to get full coverage. A half-pint seals up to a 7-gallon tank, and a quart seals up to a 25- or 28-gallon tank.
It is important to follow the instructions carefully when using this product and to remember that once it dries, it cannot be removed. It is also important to wear proper personal safety equipment and to use the product in a well-ventilated area.

A quart of the sealer is enough for a 25-gallon tank
A quart of POR-15 Fuel Tank Sealer is enough to seal a 25-gallon tank. This is because a quart is equivalent to a quarter of a gallon or 32 fluid ounces. A quart is four times smaller than a gallon and is perfect for more precise measurements.
The POR-15 Fuel Tank Sealer is a great product to stop leaks and prevent small holes from growing. It is easy to use and can be used for sealing leaking oil lanterns and HD fuel tanks. It is also non-flammable and environmentally safe.
Before applying the sealer, it is important to clean out the tank. All fuel tanks need to be cleaned before sealing as the new coating will not stick to gum and varnish. The POR-15 Cleaner Degreaser can be used to remove grease, oil, and surface debris.
After cleaning, the tank should be allowed to dry for 7 to 10 days before applying the sealer. It is a simple, single-application coating that will renew your car, truck, or motorcycle fuel tank.

To apply the sealer, first clean the tank with POR-15 Cleaner Degreaser, a non-flammable and water-based solution that removes grease, oil, and surface debris. Then, use POR-15 Metal Prep to dissolve rust, coat the tank with zinc phosphate, and etch the metal for better adhesion of the sealer.

Once the tank is dry, pour in the entire can of POR-15 Fuel Tank Sealer. Follow the directions on the can for the minimum application instructions, and be sure to look online for the full installation manual.
