Review on 🔧 GM Genuine Parts 25873576 Power Brake Booster Vacuum Check Valve with Grommet: Ensuring Optimal Brake System Performance by Orlando Mohr

Used on my 1989 BMW 325is to replace the stock vacuum fittings as they failed after 27 years and would no longer hold vacuum. I converted my hoses to -AN fittings to fix some of my vacuum leaks that required a smaller diameter hose than the original manufacturer's. This vacuum connector is perfect for the booster and for the hose I used to connect to the manifold. Holds a vacuum great and looks just like the BMW unit I would use if I still had the full size hoses.
