Kreem Fuel Tank Liner Combo Pack — 3‑Piece Kit (3 Pack), Black, Fuel‑Resistant Liner + 2 Prep Solutions

Kreem 19-103 Fuel Tank Liner Combo Pack is a three-part kit (Tank Liner, Tank Prep A, Tank Prep B) designed to seal interior tank surfaces and stop fuel leaks while protecting against rust and corrosion.

This combo pack splits into three individual components so you can treat and line vehicle-specific fuel tanks with a complete, professional-style system. The kit includes a tank liner that forms a protective barrier plus two preparation solutions that clean and etch metal for better adhesion. It’s formulated for use where a dedicated fuel-compatible lining is needed and is sized to serve a standard tank application.

How does the three-step system work to stop leaks and corrosion?

The process uses two prep solutions to ready the metal and a finishing liner that cures into a seamless protective coating. Preparation removes contaminants and creates a profile for the liner to bond, while the liner fills pinholes and creates a barrier against moisture and ethanol-containing fuels. When applied according to instructions, the result is a continuous lining that helps reduce permeation and surface rust.

• Tank Prep A: dissolves and lifts oils, varnish, and fuel residues.
• Tank Prep B: chemically etches metal for improved liner adhesion.
• Fuel Tank Liner: forms a tough, fuel-resistant membrane that seals irregularities.

What vehicles and tanks is this Kreem kit suitable for?

This combo is labelled vehicle-specific fit type, meaning it’s meant to treat one tank capacity per kit and to be used on steel or compatible metal tanks where a retrofit lining is practical. It's commonly used in classic cars, motorcycles, ATVs, lawn equipment and other applications with internal rust or minor leakage issues. Verify tank capacity and interior access before purchase to ensure coverage.

• Works on steel and similar metal fuel tanks with interior access.
• Intended for single-tank applications—check tank volume for coverage.
• Helpful for vintage vehicles, motorcycles, and small engines with rust concerns.

How is the kit applied and what should I prepare beforehand?

Application requires draining the tank, degreasing, and using the included Tank Prep A and B in sequence, then pouring and rotating the liner to coat all interior surfaces. Adequate ventilation, safety gear, and following the manufacturer’s cure times are essential. For best results, remove loose rust and loose debris before using the prep solutions.

• Drain fuel and thoroughly remove loose debris before starting.
• Follow the two-step prep: clean with Prep A, then etch with Prep B.
• Pour liner, rotate/tilt tank to coat, then allow full cure per instructions.

How long will the protection last and does it affect fuel compatibility?

Longevity depends on application quality, tank condition before repair, and exposure to ethanol-blended fuels; a properly applied liner can last years as a protective barrier. The liner is formulated for fuel resistance, but performance varies with fuel formulations and operating conditions. Regular inspection after installation helps spot wear or damage before leaks recur.

• Durability depends on prep quality, tank condition, and fuel type.
• Designed for fuel resistance; avoid aggressive solvents or additives not recommended.
• Periodic checks ensure early detection of any failure or wear.

Who this is for: The Kreem 19-103 Fuel Tank Liner Combo Pack is best for DIY mechanics, restoration hobbyists and service shops needing a single-kit solution to reseal and protect a vehicle-specific fuel tank. Choose this kit if you can access the tank interior, want a three-step system that combines cleaning, etching and lining, and need a black, fuel-resistant internal coating to address rust, pinholes or minor seepage without replacing the tank.
