Great idea Dave, I think I will give it a try. I have a couple hundred feet of medical grade tubing I think is the same diameter. All I need is some connectors.
At one time I drove a Ford 9000 daycab with the washer reservoir mounted inside the cab on the back wall. Washer fluid was always close to in cab temperature.
I still believe when ever possible keep your glass cold. If snow isn't melting on your windshield, then it can't re-freeze on your wiper blades.
I concur with Mr. Hall's assessment on the windshield speed bump. Linda, you may want to re-think the purchase of this product. If it is too late, then we await your honest critique.
I discovered Rain-X windshield wipers last winter. I like them because they have more points of articulation than normal wiper blades. Because of this they conform to the curvature of the windshield better.
The afore mentioned Ford 9000(1980's & 90's models) sucked because the wiper system was backwards. Hold your arms out in front of you with your elbows bent at a 90 degree angle. Now rotate your arms to the left; this was Fords park position for wipers. The driver's side wiper extended beyond the curvature of the glass allowing ice build up. After 20+ years the problem was finally corrected.
I am still a big fan of air driven wiper motors. Not too long ago Brenda (Bryan) and I discussed the merits of these. We both liked the fact that when returning air wipers to the "park" position they "jumped" knocking any ice and snow off. Plus one could adjust them to intermittent speed, this being before multi speed electric wipers. Ford and Mack cabovers had vertically parked wipers as did Kenworth conventionals. This allowed any melted runoff to drain down rather than on to the wiper blades.
Wow, I rambled! Not sure if anybody even knows what air driven wipers are. Just the sound they made was well...erotic???
