This is the way my Prototype was done. The 5/32 ID hose ran from the pump directly to the boom. the feed hose had a reduction barb that went from 5/32 to 1/8. A small tyrap was used to lightly anchor the hose to the boom. this made it pretty much bullet proof. If any of you decide to retro your unit in this way make sure you route the 5/32 hose as shown in the photo.

PS ignore the piece of wood and the hose looks bigger than it really is in the photo.
