Description This mounts an electric vacuum pump on your intake manifold so that you can remove the problematic mechanical vacuum pump that frequently breaks. When you install a mechanical wastegate on your truck then the only remaining function of the vacuum pump is for the HVAC dampers.  We don’t feel that this justifies still having a mechanical vacuum pump that can strand you.  We choose reliability. This is a Moab tested product. Included: – Vacuum Pump – Pigtail for Vacuum Pump – MM Vacuum Pump Mount – Vacuum accumulator bottle When you remove your factory mechanical vacuum pump you will need a shorter belt.  Because there are a few variations in length needed depending on year of truck and other modifications, we suggest you procure this locally.
