    Hi Bob,

    If you can't move what's rubbing on the hose then put a spacer in there so they can't touch and then make sure it is secured. All the planes I do rubber changes on there are many that touch and rub somewhere so I just make sure to keep these areas from touching.

    Thanks, Roger.  I’ll have to see what space is available.  You know how tight it is in there.

    Hi All

    Just a note.  You can protect tight areas of hose by cutting up one of your old ones.  Be sure to clean the bit of any residual coolant and I like to buff off the inside of the old hose with some sandpaper also.  Use a super glue,cyanoacrylate instant adhesive.  

    This is the recommended method with clearing a hydraulic governor where you have contact to the sharp edge of the hose.  The old hose bit will be a sacrificial bumper and protect your coolant line.  This is standard on the type 914 just under where the governor would fit.  I attached a bit of the IPC picture with a note.

    Cheers

    Thank you very much.  Between this and Jeff’s suggestions I’m confident I can eliminate this issue.  I believe it’s rubbing on the air box, but will confirm when I pull the hose.

    Thanks again.
