Review on 🔧 GM Genuine Parts 15-72234 156 mm Vacuum Tank with Optimum Diameter by Ashwin Chauhan

I got this GM/ACDelco vacuum reservoir to replace a 35 year old original in my 1986 GMC s-15 Jimmy that had a mounting hole punched in it. This tank is used to store excess vacuum from the engine to properly activate the vacuum controls for my car's air conditioning and cruise control as both systems require quite a bit of vacuum to operate. All in all an exact and perfect replacement for my original tank.
