Larry, I haven't a clue, myself, as to why that restrictor is needed. But in my own experience, the restrictor must be there. I had to replace that short pressure hose with the restrictor. I did it with a hose that had no restrictor. I went through 5 pumps thinking they were all bad, given the racket they were making, and three of those pumps were brand new remanufactrure pumps. I sent them all back as bad pumps. I was totally embarassed when I learned of the fix. Dennis Haynes or Scott Daniels - can't remember which - told me about having to have the restrictor else I would have lots of noise like a bad pump. Turned out to be true. Lots of noise. Replaced the non-restrictor hose with one with a restrictor, noise was gone. Just my experience.
