Vacuum ball


Well-Known Member
Did all cars have the vacuum accumulator ball under the driver front fender? If so, where does the vacuum line hook up? Is it at that 3 way check valve by the firewall off of the EGR? Because i don't have cruise control and i have an open port at that 3 way valve not sure what goes to it. Thanks!

yes, the 3 way valve connects the vacuum source and tees into the vacuum ball and HVAC.

if u had cruise control, it would tee into the vacuum ball line by the driverside fender.
