- Effective retrofit - designed for simple installation to help protect the vacuum pump from damaging moisture and debris that can lead to difficult braking

- Complete kit - includes pre-mounted pump on a sturdy mounting bracket, extension harness, grommets, and a check valve with a direct-fit connector
