7. Sealer Application
Sealer application functions as a protective measure following fuel tank cleaning. The efficacy of the cleaning process is significantly enhanced when followed by the application of a fuel tank sealant. This procedure establishes a barrier between the tank’s interior metal and the fuel, preventing future corrosion. For example, if a fuel tank exhibits pitting even after thorough cleaning, sealant application fills these imperfections, creating a smooth, non-reactive surface. This prevents fuel and moisture from accumulating in the pits, which would otherwise serve as nucleation sites for rust formation. The absence of sealant after cleaning leaves the tank vulnerable to immediate re-corrosion, particularly in environments with high humidity or when using fuels with ethanol content.
The sealant also addresses potential pinholes or weak seams that may have been exposed during the cleaning process. Chemical cleaning or mechanical agitation can reveal pre-existing vulnerabilities in the tank’s structure. The application of a sealant effectively plugs these leak points, restoring the tank’s structural integrity. Furthermore, certain sealants provide resistance to the corrosive effects of ethanol, a common additive in modern gasoline. This added protection extends the lifespan of the tank and prevents fuel contamination. An example of this is the use of epoxy-based sealants, which form a chemically resistant lining, safeguarding the tank from the degrading effects of ethanol-blended fuels.
In conclusion, sealer application is an essential component of comprehensive fuel tank maintenance.
