SUPPLEMENT: 06/25/79

SERVICE MAGAZINE, MAY 28, 1979, PAGE 1. In the article "9S8100 Tool Group Changed To Use With Fuel Transfer Pump Only", the illustration of later 9S8100 Tool Group parts shows the 9S8104 Press Fixture Assembly and the 9S8109 Screw Clamp Assembly as "not available separately". These parts have now been released for parts service, and will be available separately. To correct the illustration, remove the words "not available separately" from the identification for each of the above parts.

--------------- END SUPPLEMENT ---------------

The 9S8096 Seal Installer Sleeve for water pump seals has been removed from the 9S8100 Tool Group, and the name of the group changed to "9S8100 Tool Group-Fuel Transfer Pump". Removal of the water pump tool from the 9S8100 Tool Group will permit the group to be ordered for fuel system specialization areas, where water pump tools are not desired. Formerly, the water pump seal installer was sent as part of the group, but was not needed for fuel system specialization areas. The 9S8096 Seal Installer Sleeve for water pumps is available separately, and can be ordered for areas where it is needed. Some earlier groups are still in parts stock, and these groups have the water pump seal installer.
