Fuel Pro Check Valve Kit for Davco

The Automann 572.DAV101132AM Fuel Pro Check Valve Kit is engineered to restore the internal check valve mechanism in Davco 382 / 48X style fuel/water separators. This kit consists of the ball, spring, and retainer used in the original 101132DAV check valve assembly. Over time, fuel system contaminants, corrosion, or wear can degrade the check valve’s performance, allowing undesirable backflow or reduced fuel delivery. Installing this kit restores proper valve action and helps maintain system pressure and filtration performance. The kit is used in Fuel Pro / Davco assemblies across PACCAR, Kenworth, Peterbilt, and other diesel chassis employing the 382 / 48X design. This small but critical service item aids longevity of the separator system and helps prevent damage to injectors or pump starving events. Wofford Truck Parts offers this kit to support maintenance operations and optimal fuel system reliability.
