The POR-15 Fuel Tank Repair Kit (MPN 49239) is a complete metal tank restoration system for anyone dealing with a rusted, leaking, or contaminated fuel tank. It's built for automotive, agricultural, and industrial machinery tanks running gas, diesel, or diesel exhaust fluid, and it treats tanks up to 25 gallons with one quart of sealer. Rather than replace a tank that's started weeping at the seams, this kit stops rust, seals pinhole leaks, and leaves a permanent non-porous coating bonded to the metal. It's a practical fix for restoration projects, farm equipment, and older vehicles where a factory replacement tank is expensive or no longer available.
The kit ships with everything the job requires: two quarts of POR-15 Cleaner Degreaser, one quart of Metal Prep, one quart of Fuel Tank Sealer, reinforcing fabric, a brush, and detailed instructions. The three-step process cleans, etches, and seals. The sealer chemically bonds directly to metal, including rusted metal, which is what separates it from a simple patch product. Once cured it forms a flexible, non-porous film that resists all fuels, alcohols, additives, and solvents, including ethanol blends and Stage 2 fuels. The coating is non-flammable and environmentally safe. The reinforcing fabric backs up larger seams and weak spots so the sealed area holds under pressure and vibration. If you only need the coating itself, we also stock the fuel tank sealer in quart size.
Use this kit when a metal tank shows surface rust inside, a pinhole leak, or fuel staining at the seams, common problems on stored vehicles, vintage motorcycles, tractors, and generators. Surface prep is the difference between a seal that lasts and one that fails, so the Cleaner Degreaser and Metal Prep steps matter as much as the sealer itself. For severe internal rust before sealing, pair this with one of our rust removers. Browse the rest of our oils, fluids, and sealers for the prep chemicals, threadlockers, and gasket sealants that go with a tank or fuel system job.
The kit includes one quart of POR-15 Fuel Tank Sealer, which is rated to treat metal tanks up to 25 gallons. For larger tanks, you would need additional sealer beyond what ships in the kit.
Yes. The sealer chemically bonds to metal, including rusted metal. The included Cleaner Degreaser and Metal Prep steps remove contamination and etch the surface first. For heavy internal rust, treat the tank with a dedicated rust remover before applying the sealer.
The cured coating resists all fuels, alcohols, additives, and solvents, including ethanol blends and Stage 2 fuels. It also works with diesel and diesel exhaust fluid tanks. The non-porous film is non-flammable and environmentally safe once cured.
Two quarts of POR-15 Cleaner Degreaser, one quart of Metal Prep, one quart of Fuel Tank Sealer, reinforcing fabric, a brush, and detailed instructions. That covers all three steps: clean, prep, and seal.
No. This system is formulated for metal tanks and chemically bonds to metal surfaces. It is not intended for plastic or polyethylene tanks. Verify your tank is metal before starting.
