Feuling Parts

Piston Cooling Jet Pressure Tester


Feuling's pressure test tool for assembled engine cases is a "must" for any M8 or Twin Cam builder according to CEO and 'Guru of Go' Luke Leatherman.




"It allows builders to test the piston cooling jets while installed in the engine case, even with the cylinders on, to ensure proper operation."

Leaking or prematurely releasing piston cooling jets can cause high engine case oil levels (sump) and lower oil pressure to the lifters' bores. Piston cooling jets that fail to pop off will reduce piston lubrication leading to increased heat and wear. 


"With this tool, you'll be able to verify operation prior to start up or diagnose an issue."
