I initially just replaced the small (pesky) piece of hose on the block, but it leaked. It is a real pain trying to get the new little hose on the block and pipe, and secure the hose clamps, in such a tight space. The second time around, I decided to go with the bypass, and it was way easier. This time I didn't bruise my arms!
I found that O'Reilly's carries Gates Green Stripe Heater Hose and Constant Tension Hose Clamps. Call in advance to make sure they have the Gates Green Stripe 5/8" inner diameter and the Constant Tension Clamps. The clamps were in the back, not on the shelves, and they ordered a box of Green Stripe just to cut me off a few feet. This is much cheaper than ordering a PHH "kit" online.
To remove the old heater pipe, the "wiggle until it breaks" method did not work for me. I had to bend it out of the way and use a 12mm open end wrench with a ratchet on one side to remove the bolt by the firewall. It was still a pain even with that handy little wrench.
With the old pipe out and the leaky hose removed, installing the bypass was cake.
I have been wheeling with it like this for a month and it hasn't leaked.
