I followed advice from several listers -- cut off end of hose and re-attach.
The hose is a bitch to remove!
Two heat guns were used to warm up the rubber hose in order to make it more
I had to be careful with the prying so as not to break off the reservoir
nipple. On the 100q, I had to split the hose end for about 1/2" in order to
get it off the nipple.
1/2" of hose end was cut off and re-attached using 2 new hose clamps.
On the 5000q, I added 2 more hose clamps to the existing setup.
The reservoir nipple is long enough to fit two clamps on the hose end behind
the nipple barb.
I added the second hose clamp to fit right over the nipple barb.
So far, so good.
For a leak indicator, I wrapped a folded over paper towel, held in place
with tie wrap, around the connection. No leaks so far.

> To fix the problem temporarily, I want to replace the hose end with new
> Cut off about a foot from the end of the hose.
> Add a copper or brass tubing to inside of the old hose.
> Slip new hose over brass tubing.
