Review on Dorman Help 47392 Vacuum Caps by Jack Harrell

This vacuum caps really got the job done on my automotive fuel system .As a result of using this product, I found that my car now runs more smoothly and efficiently. It's a great product for anyone looking for an affordable, yet effective solution for their fuel system issues. The only downside is that the package only comes with a limited number of caps, so if you have a lot of vacuum lines to cap off, you may need to purchase multiple packages..
