I have successfully done the rivet repair many times.  Best is to use a countersunk rivet and then coat the rivet area with silicon sealant before installing the hose.

      Please note that I will be away from my business travelling from November 16 until April 30, 2016.  Parts orders will be processed although not as quickly as usual.  I will always be available for contact by E-mail.  If you phone your call will be addressed by Steven and he will either call you back or advise you to contact me directly by E-mail.  

Cheers,
