Yes, you can. Berryman B-12 Chemtool Fuel System Cleaner (part #0116) is completely safe on most components that come in direct contact with gasoline. However, you may still need to run a detergent-based cleaner afterwards if the deposits/buildup are severe. If that’s the case, then Berryman B-12 Chemtool Concentrated Intake Valve & Injector Cleaner (part #3012) or B-12 Chemtool Total Fuel System Clean-Up (part #2616) would be your best bets.
