The Delphi Product & Service Solutions Fuel Tank Cleaning Kit helps improve the longevity of fuel pumps. Debris and contaminants can collect over time inside a tank, which can clog the strainer, forcing the pump to pull more current and amperage. The fuel tank cleaning kit includes a cleaning solution, gloves and a lint-free cloth. The low-suds cleaning easily treats and rinses up to a 40-gal capacity fuel tank. It removes microbial growth in the tank, breaks down varnish and gel from ethanol and minimizes sludge and other fuel contaminants.
