^^^I would add to bluefront's #2 comment, that you should run some Heet through it to get all the water out, then add the fuel cleaner. most fuel cleaner will remove water, but Heet is really good at just that one task so I always add it. I have a friend who sells used cars, lots of them, in AZ and he had a Honda that was missing and says he's going to have his mechanics probably rebuild it if he can't figure out what's wrong. I drove it 100 ft and told him to put Heet in it. Problem solved. True story. Temp and pressure changes, as well as contamination, will cause water to build up in places, mostly in the filter, and bubble up, inhibiting flow.
Life's short and you only live once. SO FLOOR IT!
