been trying to get my hydraulic clutch line sorted.,Problem being the st170 clutch line is a bigger bore pipe than the pedal box takes.The pedal box uses a 3/8 unf fitting and the focus line uses the push in fitting with a circlip . i need a place or fitting to drop the to the pedal box size which takes brake line sized copper pipe. tried pirtek and no luck, norton hydraulics (sold me a compression fitting saying it will step the bore down and didnt ) any help greatly appreciated as annoying me now.
