9071 Piston cooling jet tester block kit

This complete piston cooling jet tester kit from Feuling is a must-have for any shop working on 1999 to 2017 Twin Cam or 2017 to 2026 Milwaukee-Eight engines. Sold as a kit, it includes the tool plate, pressure gauge, regulator, and all necessary hardware to diagnose the health of your cooling jets. Properly functioning jets are critical for piston longevity and managing crankcase oil levels. This kit helps you identify leaking or clogged jets before the engine is fully assembled, preventing potential sumping issues or piston damage. If you do not already own the Feuling pressure relief valve tool, this is the comprehensive package you need.
