SUPER FUEL MANAGEMENT UNIT (SFMU),
CONT'D.
NOTE: If the rate of gain that the 2.22" disk gives is still too high, ring #6X070-041
may be used in conjunction with assembly #6Z170-010 or #6Z170-015. #6Z170-015
will give approximately 1.5:1/2:1 rate of gain. #6Z170-015 will be slightly higher. These
parts are available separately through Vortech.
