Shertex,

The True "Afflicted" will R+R AND RePlace the Vacuum Pump @ 100K Miles.
(As a Prophylactic Enterprise.)

Your '92's "RePLacement" V.P. has 193 K Miles on it !!!!

The O.E. V.P.'s design and execution is an Invitation to FAILURE!!!

1.'Junk "Cast" Crap metal Housing and Fitments.
2.'Junk Semi-metallic "Ramps" device for powering the V.P.
3.'Even more "Junkiness" in the Sub-Standard Bushing holding the "Timer".
4.'Etc.,Etc.,Etc.

At almost 200K miles on a V.P. You're not Obsessing to think about RePlacement !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
