Feuling PSI Tester - Camplate Relief Valve Tool for Harley & Indian Twin Cam
About Feuling
Feuling Parts specializes in the internals that decide whether a big-inch V-twin lives or dies — oil pumps, cam plates, lifters, pushrods and camshafts. Its high-volume oil system components are a standard upgrade on high-mileage and high-output Twin Cam and Milwaukee-Eight engines.
The Feuling PSI Tester is an invaluable tool for Twin Cam engine builders, allowing for precise bench-testing of camplate relief valves. This specialized tool enables you to verify pressure settings, check valve seat and seal integrity, and even adjust spring tension to achieve your desired pop-off PSI before engine installation. It's a critical step for ensuring optimal oil pressure regulation in your Harley-Davidson or Indian Motorcycle Twin Cam.
