My tank has an internal fuel pump and fuel strainer assembly consisting of a mix of plastic and metal parts. Is it safe to use KBS Klean on these parts?

Yes — you can absolutely use KBS Klean on the plastic and metal parts inside a tank with an internal fuel pump and strainer assembly. KBS Klean will not harm plastic, and you can run it safely through the fuel pump to clean it out along with the rest of the tank.

Safe on Mixed Materials

Whether the internal assembly is plastic, metal, or a mix of both, KBS Klean will not damage those components. It can be flushed through the fuel pump itself to clean out residue and debris.

If you're cleaning the tank as part of a full rust prevention and sealing project, KBS Klean is the first step of the KBS Tank Sealer System. Review the complete Tank Sealer Directions for the full process, and reach out if you have additional questions.
