Complete Fuel System Cleaner


Carbon, lacquer and sludge deposits continually form on fuel system components – ultimately hindering the engines performance by restricting the efficient flow of fuel and air through the engine to the combustion chamber. These deposits cause hard starts, rough idling, hesitation, surging, reduced fuel economy and increased emissions – robbing the engine of it’s maximum performance potential. Gumout® Professional 1-Step Complete Fuel System Cleaner aggressively cleans sludge, carbon and varnish deposits from critical engine fuel system components which helps improve engine performance and restore lost horsepower.
