Check rubber sleeve
To prevent filter replacement problems caused
by premature corrosion of the locator pin (7) in
the filter receptacle, a rubber sleeve (9) was in-
stalled on units with S/N 10518 and up.
Defective or missing rubber sleeve (9) should be
replaced or retrofitted (refer to service bulletin
no. 1998-045).
