01539-0 Briggs and Stratton Pressure Washer - Overview

I order the part from this site and received it within a week. the only problem was that spring was missing out of the sealed bag. NO PROBLEM!!! I cut a ball point pen spring to fit and everything works just fine. You just have to remember to put the spring in first, then the ball bearing and then the rubber o-ring.If you put them in backwards you pressure will fed directly into your chemical container!!
