I have seen lots of threads on installing the ball valve on the water line so it can be shut off prior to towing, but none that address my question. I was going to install this valve on my 2015 Spark 3Up but had the following question. I wanted to make the hose longer and use a couple of elbows so I could position the valve right inside the access panel making it very easy to access and ensure its position prior to riding. However I can't remember where but somewhere I remember reading that the hoses in the closed loop cooling system should not be replaced with longer or shorter hoses. I was wondering if this holds true for the sea water supply system or if It would be safe to make that line longer? In total I would probablybe adding about 12 inches to the hose length.
