I don't doubt you have a leak somewhere..
I would however, ascertain exactly where you're leaking fluid from first before replacing the pressure hose as a whole..
It could be something as simple as just replacing a Teflon seal, which are easily obtainable/cheap..
I have my doubts the line itself has failed, unless it was damaged when the rack was changed out..
