But, was it a pour-in-the-tank can, or aerosol?  I suspect it was a Berryman 
product.  If it was, they are not too expensive and work well.  Helps mileage a 
little, but not much.  An ounce or two a gallon will clean out the system.
Acetone, one of the likely ingredients, is supposed to help mileage.  I put 
some in my 450 when I first got it, but not for mileage - it was to clean the 
carb.  It works for injectors as well.
It lost most of the hesitation under hard acceleration after a few runs with 
the acetone.

I just got a can of some sort of fuel system cleaner at the auto parts store. I 
think it was called B12 or B31 or something. I remember the 'B'. It wasn't the 
usual add-with-gas stuff though, I just asked the guy behind the counter and 
then grabbed the largest can he had.
