Kreem Fuel Tank Liner Combo Pack 3-Pack Black — 3-Step Prep, Corrosion-Resistant Seal

Kreem's 19-103 Fuel Tank Liner Combo Pack is a three-piece, vehicle-specific kit that prepares, primes, and coats fuel tanks to stop corrosion and seal small leaks.

This 3-pack includes the Fuel Tank Liner plus two companion solutions (Tank Prep A and Tank Prep B) designed to be used together as a complete treatment system. The three-step process cleans and conditions the metal, applies a corrosion-resistant bond coat, and finishes with a durable inner lining to protect against fuel and moisture. The kit ships in black and is sized to cover a typical single fuel tank; because the pack contains multiple units it can be split across separate tanks or used sequentially for larger jobs.

How does the three-step process protect an aluminum or steel fuel tank?

The system works in sequence: Tank Prep A removes contaminants, Tank Prep B neutralizes and etches the surface, and the Fuel Tank Liner adheres to form a durable barrier. Together they reduce the risk of rust formation and can slow the progression of existing corrosion by sealing exposed metal from fuel and water intrusion.

• Step 1: Degreases and strips old residues for better adhesion.
• Step 2: Chemically conditions and etches metal for primer bonding.
• Step 3: Applies a black inner coat that resists fuel and moisture contact.

Will this kit stop active leaks or repair major damage?

Designed to stop minor leaks and to seal pinholes, the liner is not a substitute for mechanical repair of structural damage. For hairline leaks and internal porosity the product can provide an effective seal, but larger cracks or holes require welding or replacement before lining.

• Effective on pinholes, porosity, and small corrosion-weakened areas.
• Not intended to replace welding, patching, or tank replacement for large breaches.
• Use manufacturer-recommended safety precautions when testing for leaks after application.

How much coverage will one pack provide and can the set be split?

The combo pack is supplied as three components sized for a single standard tank but can be split to treat multiple smaller tanks or provide touch-up service later. Exact coverage depends on tank interior complexity, thickness applied, and preparation quality.

• Pack includes enough material for one typical passenger fuel tank at recommended thickness.
• Multiple tanks can be treated by splitting the components between jobs.
• Thin, even coats increase usable surface area compared with thick, uneven applications.

How do I apply the products safely and get the best adhesion?

Follow the sequence: clean and dry the tank, apply Tank Prep A, rinse and neutralize with Tank Prep B, then apply the Fuel Tank Liner per label instructions. Work in a well-ventilated area, wear appropriate PPE, and allow full cure time before refueling or reinstalling the tank.

• Thoroughly drain and ventilate the tank before starting work.
• Use recommended cure times and temperature ranges for optimal bond strength.
• Mask openings and use venting to ensure even coating and solvent escape.

Who is this for: The Kreem 19-103 Fuel Tank Liner Combo Pack suits DIY mechanics, restoration shops, and fleet maintenance teams who need a vehicle-specific, multi-step solution to prevent rust, stop minor leaks, and extend tank service life. It’s most useful when tanks are structurally sound but show internal corrosion, pinholes, or porous metal—when a protective internal coating can restore function without full tank replacement.
