Berryman B-12 CHEMTOOL TOTAL FUEL SYSTEM CLEAN-UP (part #2616) is our strongest detergent-based fuel additive for gasoline engines and will thoroughly clean the fuel pump, fuel lines, fuel injectors or carburetor(s), intake valves, and combustion chambers. If this addresses the problem, then you should also regularly use Berryman B-12 CHEMTOOL FUEL SYSTEM CLEANER (part #0116) as a preventative maintenance product.
