Hello, I have an excell power washer (http://www.excellpressurewasher.com/vr2522.asp) I recently broke the hose and had to buy a replacement. The power washer ran great up until the replacement. I bought the proper hose (1x4 x 25") made by briggs and stratton. When I tried it out, the power washer would squirt water through the line but I have no pressure. Any idea's on what might be causing this?
