Windshield washer fluid line failed... Have question.

[Waterloo]

Ok, 2008 ProStar, going down the road and my "Low Windshield Washer Fluid" idiot light came on... I just filled the bottle the other day... I found that the plastic line that runs from the pump on the bottle to the windshield had rubbed against the chassis and sprung a leak. I tried splicing the line with a quick connect, but the line was just a hair to big to properly seat. So, anyone replaced this line with regular vacuum hose, or is a trip to the dealer needed to get the correct sized line? It looks to be a very oddball size compared to the rest of the plastic air lines on the truck. I called the dealer, and they had no clue on the actual size of the plastic line, or if available.

Anyone replace this line, and or splice it? If you spliced a new section in, what did you use to do that?
