Popped a hose on bucket roll where it articulates. How many PSI hose do I need to get replacement made? Gonna do all four because they are original,cracked rubber,exposed braid. LOL! This was a "someday" project that turned into "current" project.

Should be 1825 PSI, unless someone has messed with the relief valve.

Google is your friend (except for that free speech thing...)

My 7G had similar pressure, High volume.  I used double wire braid lines actually rated over 10,000, but shock loads will be considerably HIGHER than operating pressure.
