Brand new ACDelco two-way vacuum line check valve for 1986-1987 Buick Grand National, Turbo Regal and 1987 GNX. This check valve splits a 7/32" vacuum line into two 5/32" vacuum lines - one for HVAC control, and one for the cruise control servo and cruise control vacuum tank.
This part replaces and supercedes the discontinued factory original all-black ACDelco #14056648 check valve and will fit and function as original.
