    clutch pipe for marina based roadster

    Have replaced the seals in master & slave cylinders but have a problem with leaking fluid. Thinking of re-tapping threads on the pipe, does anyone know if they are 3/8 unf?
    Thank you

    All the threads on a standard Marina hydraulics are UNF.
    Not sure why you should want to retap any hydraulic ports, a properly formed copper pipe, when tightened by its retaining screw, will deform the copper into its seating.
    Perhaps you can be more specific where the leak is coming from.

      Hi Vic,
      Have you had a close look at the union where it clamps on the swagged pipe, if it's a brass fitting and has been over tightened these can crack and the thread will bottom out before it clamps the copper pipe.
      Best Regards

        Thank you Steve & Graham. Should I require a new pipe, where would be the best place to go? I bought one on line but pipe diameter is not correct, smaller like a brake pipe.
        Thanks,
        Vic

          eBay has a clutch hose here or there same size across the Marina/Ital range whether 1.3, 1.8, 1.7, 2.0. So not sure where it what you bought previously.

          Still confused, even more, are we talking e Red plastic pipe or something else?
          The red pipe has pre formed (metal) ends, not deformable to the same extent as copper.
