Zodiac Polaris 360 question

I have a zodiac Polaris pool cleaner.  The cleaner is several years old, and with your company supplying the parts I rebuilt it.  However over the years, it appears some changes were made.  My system uses a .750" feed hose with a .750" feed pipe.  Now I cant find a .750" feed pipe to fit my system.  Now, I need answers to the following questions:

1.  is the .750" feed pipe still available?

2.  if so, where can I get it?

3.  if not, what do I need to convert my system?

Thank You
