FilterBOSS DFP500FG
Last night I received my new FilterBOSS model DFP500FG. Very cool! They packed it very well in blown in place foam in plastic bags. They even ship it under vacuum so you can see if any of the fittings have loosened. It seems bigger than I remember in the boat show. But it looks like it will fit perfectly where I intended to put it. I read the manual cover to cover last night and did a lot of thinking about where and how to mount it. I have decided in order to clean the tanks easier I need to isolate them. All three tanks are now one system with only one fuel return to the center tank and one fill hose. I will add two more fill hoses and deck fittings. I am going to put a four valve fuel manifold and direct the engine return fuel flow into one of the three tanks (the fourth is for the filter bleed return). And then use the valves on the tanks to pick which tank the fuel comes out of. I intend to mount the FilterBOSS on the board holding the tanks with the top of the mount just even with the bottom of the tanks. So it will be just under the tanks, and the tank valves. That should be just about perfect. The outlet will be just above the engine fuel inlet so all the fuel will be flowing down hill. Perfect. 
I am thinking of putting the fuel return valve manifold on the top left hand corner of the FilterBOSS mounting panel. That way it will be near the fuel tank selector valves, and easily accessed along with the filter change over valves as well as giving me enough room to clearly label each valve. This is working quite well so far. I am very pleased. More pictures will be posted as soon as I get something mounted and tubing installed so stay tuned.
