Trying to cure the slow leak down on an '86 Force 125. Pulled the valve body apart and replaced the o-ring on the shuttle valve, took the plug valves apart to replace the seats, but there weren't any there... Should it have seats on the needle type valve?<br /> Also pulled the top part of the valve body off, when reassembled, the pump runs but no pressure builds, does anyone have a diagram of the valve body they could email or fax to (757) 836-3432?<br /> Thanks, in advance...
