Berryman B-12 Chemtool Total Fuel System Cleanup (part #2616) is not ideally suited for that application.  However, if it’s all you have, then it may do the job for you.  Use it in the same manner that you would use B-12 Chemtool Fuel Injector Cleaner (part #0116) except maybe let it soak a little longer.  Because 2616 was formulated to work differently than 0116, you should change the engine oil and filter after you’ve completed the soak.
