The pump is probably not leaking. You have a bad hose. Find and replace the hose then flush the crap out of the system to be sure you have all of the "BAR power steering repair" junk out of the system. You should NEVER use snake oil to try and fix a problem, it will never work and usually causes more problems than you originally had to start with.
