10 yr old 3200psi 4 gal 11hp honda AR pump blew out the hose on thurs. My guess is the unloader valve failed and the pressure continued to build and popped the hose out near the gun. Is it ok to just get an unloader or would a whole new pump and unloader be wise. Keep in mind I just went out and bought a new one to finish the job that day. The last time a machine went on me the unloader simply wouldn't let the pressure build.
