Am I Crazy?

Or just going to blow myself and my boat up?

OK, so here's my thought. My boat is suffering from the dreaded clogged VST filter which I have to get fixed. So I have been thinking about my fuel and grunge in the tank. I was wondering about a way to filter the fuel and get what I can cleaned out.

What if I connected a line to the outlet on my fuel filter (Yamaha 10 micron) to a universal fuel pump that I already have and then a hose back into the fuel filler. In concept the fuel would recirculate through the filter and back into the tank just like water in an aquarium (where I got the idea). I could let it run for awhile and then change filters.

Isn't this basically what fuel polishers do?

Heres how I have been doing it for years.

Hope it helps you just need a good fuel pump .

I use a high volume explosion proof electric fuel pump (omc primer pump) and run the fuel through a waterseporator. I usually run the tank almost empty and just keep pouring the 5 gal back in at least 4 times checking the filter each time. I do this every 2 years and you wouldn't believe the crap that you pick up. Install a new filter and your ready for the new motor.

You might try filtering it through you 10 micron filter for a round and then put on a 2 micron filter and run it through again just to make sure. I've decided not to run a 2 micron with my Yamaha since it's not reccommended and my engine is under warranty. But what your doing doesn't involve the engine so you could add a little measure of filtering by doing a second round with a finer particulate pulled out. Good luck with it, I've already changed out a high pressure pump because of the dreaded VST issues so I feel your pain.

That is essentially the same system we use on the boat I work on, its called a fuel polisher. Basically there is a pump at the bottom of our tanks that pumps the fuel through a filter then puts it right back in the tank.
