Feuling Parts - Ref. 9071
Pressure testing kit for piston cooling jets, designed for tuners and mechanics who want to bench test the piston/cylinder head cooling circuits. A standalone and complete tool, it includes the support plate, pressure gauge, regulator, and all necessary fasteners to carry out quick and repeatable checks on Twin Cam and M8 engines.
Practical in the workshop or on the assembly bench, this kit helps you check the sealing and balance of the jets before installing the pistons and cylinder heads, thus limiting the need for disassembly returns. Ideal for Vintage/Classic enthusiasts and touring riders concerned about a robust installation on their big Harleys (Twin Cam / M8).
