Need new water preasure hose!

[robert jordan]

Now that the Tygon hose issue has been thoroughly discussed lets talk water preasure hose for a minute.
Took my Action out today and noticed water running down back of the dash all over electrical wires and such so I headed for boat ramp and back home (short trip) Must be hose going to my Livorsi water preasure gauge, I know that's a no brainer! Real question is can I just replace the hose? I would think so. But what should I get and is there a braided hose that would keep this from ever happening agin? Also what size do I need? And this is it right, see pic? Thanks guys!
