Need more fuel

[Scott Linder]

dzorde,

As a injector reconditioning shop we can supply a set of  flow matched  24 lb
injectors the next step up for $ 24.95 each  ( 199.60) per set of 8  ( exchange)

The next step from the 305 is the 350  rated on our meters at 50 mil = 305  and
60 mil = 350.
Usually we have these in stock.  Check us out at:
