I have a theory...

If you look here, https://**************.com/store/self-leveling-suspension-sls-high-pressure-hose-replacement-kit-w-instructions , You will see what I am talking about. He includes a smaller diameter plastic line with his kit. Why? I think this is used to push the plastic pieces in the OE hose into their proper placement.

I replaced my hose recently, and put those plastic bits back in the hose, but I did not bother to space them like they were in the OE hose; I believe this is why I have a new 'whir' noise that is directly related to engine RPM.

I was hoping to read the PDF that you get when you get this kit from MS... Can anyone help me?
