I has been my exsperience when ever water is found, replace filter, water does not clean well after soaking in and of course gas does not remove water. So I would change all filters, blow the tank and lines with air, and clean the carb. It sounds like a little work but compared to down time and a workers labor............. I always add some heet to my gas cans when ever the weather starts its fall changing. condensation will raise hob with fuel systems, just an added precaution that pays off in down time.
