I just finished rebuilding my J/30 and redid the fuel system while I was at it. The previous owner had installed a second fuel pump presumably because they couldn't get pressure. As it turns out the problem was simple - the tank was dirty. If your tank is dirty, changing your filters will only solve your flow problems for a short time. Based on the fact that new filters work temporarily, I'd say this is almost certainly your issue.

I pulled my tank, removed the inspection port and was able to hand wipe out much of the tank by hand. Then I sloshed a half gallon of acetone a cup or so at a time to get the gunk out of the places where I couldn't reach. I pulled a TON of grime out of the tank! I got rid of the extra pump and the fuel pump on the side of the engine works great and I'm pretty sure my filters will last for a while now.

I ended up strapping the tank in so I could pull it and clean it fairly easily.

BTW: I couldn't be happier with my boat. New core in the bottom and decks, new epoxy bottom, fresh awlgrip, engine refit, etc. I've gotten a mountain of unsolicited compliments! Can't wait to do a little PHRF racing in my area to see how it stacks up.
