I went through this same thing. Had a leak in that short hose. Replaced
it with a re-built from a list vendor. Buzzed like crazy. I thought it
was the pump. Changed the pump three times, before someone told me about
the restrictor that MUST be there. The replacement hose didn't have it.
I found a used hose with the restrictor. No more noise. Every pump that
I thought was faulty worked just fine after getting rid of that rebuilt
line and putting a factory hose with the restrictor back in. I would
suggest you find a used, serviceable hose from one of the good Volks on
line that keep such things. Cheaper that way. Otherwise, bite the bullet
and get a new one - even though they are pricey.
Good luck.
