Berryman B-12 Chemtool Fuel Injector Cleaner (part #0116) is not the right type of cleaner for that application.  Instead, we recommend using Berryman B-12 Chemtool Thru-Rail Injector Cleaner (part #s 1120 & 1126).  Both products are formulated with the right type of detergent for that application.

1120 comes pressurized and is designed to hook directly to the fuel rail using customer-supplied adapters.  1120 requires a tap for 1/2”-16 righthand Acme thread for self-sealing valves which can be found on Amazon for $10-15.  Alternatively, 1126 is a pourable product for use with a canister system (such as an OTC model) and is then pressurized onsite with shop air.

Hope this helps.  If you have any additional questions, please let us know.
