Looks like the filter is doing what it is supposed to. I've seen a lot worse after about 1/2 your hours.
We burn a little less than 7 gallons / hour, but of course, a lot more than that goes thru the filter every hour.

The fuel has been refreshed regularly over the 13 months since I changed the filter (422 hours x 7 gph is almost 3,000 gallons, and we hold only 1,000). But at the time the filter was changed, we hadn't put much fuel through the system in the previous year, so some of that filter's life was filtering some not-so-fresh fuel.

We've bought fuel in Nassau, Providenciales, and Salinas (PR) during that time. Since all fuel goes through the 2 micron filter before it goes into our "day tank", and that filter has never gotten really cruddy, I feel like we've never gotten any bad / dirty fuel.

As noted in the OP, the filter in the pic is 10 micron, and everything goes through 2 micron on its way into our day tank.
