i redesigned it to be 9 feet long. it meant using a space that had previously been very useful storage but it was worth giving it up to get a shorter run.
the difference is in the number of strokes you have to pump after each use. i pumped about 50 strokes with the old 22 foot system. now i pump about 20 times with the 9 foot system. this is with a raritan phII manual head.
