Un hook line from pump to carb/carbs carefully check for good flow.If a good strong flow carbs<br />probably need rebuild.If weak check for colapsed<br />primer bulb if collapsed line is restricted<br />between tank and pump or vent is plugged.<br /> Check lines,connections,and connectors.Dont forget diptube in tank and whatever filters in the system.If all checks out rebuild pumps.<br /> If they are old do pumps anyway.Dont forget to get a ser. manual before starting any repairs.<br />Try the library,NAPA,the tab at the top of this page,amazon.com,ebay,etc.

thanks again SS, have the seloc manual but<br />sometimes you guys explain better. new gas tank<br />and supply hose/primer. all fuel lines look great<br />(on the outside), who knows how they look on the inside though. isn't the pump/filter kit just<br />a filter and a O-ring? I'm just learning OB's<br />and trying to do easy jobs first. <br />regards,<br />my
