Wow, that looks to be about $2,000 worth of fuel polishing equipment right there. I have a similar set-up, but mine only uses one Racor filter. I can polish about 60GPH with it.

The two filters on the left I already had onboard, so the one on the right (use specifically for the polishing circuit, was the only one I had to buy. All-in-all, putting this rig together cost me about $800.
