Product review (5 stars): Worked fine for me
Worked fine for me.  developed a leak in my 15 year old feed hose and needed a replacement.  Ended up with this kit.

I expect that this hose material will develop a leak just like my old one did, but the old one lasted 15 years before it developed a leak so I guess I can't complain.

Only real problem I had was that the hose is very stiff, and naturally wanted to bend the wrong way.  I didn't try a heat gun on low to soften it up, perhaps that would have helped.  Even without the heat gun, I eventually got it installed OK.

My only gripe is that if the hose was just a little bit longer (perhaps an inch) it would have made assembly much easier in my application.
