Came off a 1991 Mercedes 560SEL. 
This unit was tested before removal and it is in good working condition. 
This unit has about 163,XXX miles on it. 
It holds vacuum without an issue. 
None of the fuel line ports are stripped. 
This is a genuine Bosch unit. 
This unit will fit most Mercedes W201, W124, or W126  from 1986-1993. 
PLEASE MAKE SURE THIS WILL FIT YOUR VEHICLE BEFORE PURCHASING!!
Thanks!
