Review on 🔧 Dorman 917-146 Vacuum Pump Repair Kit: Perfect for Restoring Vacuum Performance in Select BMW Models by Greg Mahoney

Gaskets and bolts fit my 08" BMW X5 4.8i perfectly. I read online that you need these large bolts when replacing gaskets so the fact that they come with it helps. After I have replaced both seals and reinstalled I haven't had any leaks in 2 months.Tip for anyone installing this it will take a lot of wiggling and pushing to put the vacuum pump back in place until the part snaps in. Inside the pump is a part that is oriented a certain way for proper installation, so look at it and align it before you put it back in. Oh, and lubricate the seals before installation so nothing dries out after installation or tears.
