I'm going to try to replace the PHH hose either this weekend or next. At the auto parts store, I had a discussion with the parts counter guy about the varying quality of hose. I also told him I need a hose for a high vibration/heat/anti-freeze/dripping oil/grease location that was a PITA to get to so I wanted to minimize the number of times doing the job over the life of the vehicle. He recommended going to a marine supply store as their hoses are double reinforced (automotive tends to be single if you look at a cross sectional view). Today I went and picked up a foot of hose from the local marine supply shop ($3) and had the same discussion there. He thought the hose he had would be good for the job. You can see the second reinforcement layer when looking at the cross-section. It is slightly thicker, which may make the install harder. I'll let the board know how it goes. (Oh, and someone stop me if this sounds like a bad idea)
