Review on 🛠️ Dorman 904-810 Dodge Models Gear-Driven Mechanical Vacuum Pump for Enhanced Performance and Reliability by Brennan Buckley

The first vacuum pump I received from this dealer leaked through the stuffing box and I had to request another pump which was shipped immediately and I received it two days later. These pumps appear to be cast/forged in Argentina and the bolt holes that the steering pump mounts rest in will not allow the OEM skirt nuts to sit flat unless you saw off the rounded corner or used regular nuts with lock washers. If your Dodge Ram is 98.5 or newer, this pump does not have a one-way check valve like your OEM vacuum pump, but it works great without it. Before proceeding with the installation of this pump, discard the flimsy gasket that comes with the pump and purchase an OEM or Cummins gasket. It's metal centered and thicker so it won't crack when you try to install the vacuum pump. No core return is required, so I rebuilt the OEM vacuum pump and packaged it as a replacement. The price of this pump is ok compared to what an OEM pump would cost.
