    Onan 4000 fuel pump

    The previous owner of my 21G did not run generator .I fill gas tank and got generator to run for a few minutes then it died and wont start.I checked and pump is not pumping fuel to carb.I also used a vacuum pump and was able to pull fuel through pump and filter so I think pump is bad ,less than a year old.My question is ,what is the best replacment pump? Thanks
