I found a used supply/return three way valve that I use....it looks like two valves stacked on top of each other with a single handle on top....one movement and the supply and return are both switched....sooo sweet.

Just curious where is the shutoff valve on the bottom

of each tank?

The same appears to be true for the water tank">fresh water tank (red arrow). Now I'm not advocating drilling holes in the bottoms of tanks but more of a siphon that picks up about 3/4 of the way down into a tank, out the top across to the other tank and back down 3/4 of the way. If a constant syphon was maintained it would level both tanks (eventually depending on size of hose).

Frz, I don't know of too many boats in this bitterly cold part of the world that need fuel polishing systems. Maybe it's different out there in Winterpeg!

I don't really care about CG regulations cause I work there!

I'm really thinking of ways I can make this as simple and hands free as possible. We're only talking about 40 gals in each tank. I'm more concerned about having the fuel return going to one tank and forgetting to switch over and possibly overfilling a tank. Dunno but that sounds like it could happen.

Glad you brought that post up Chief. I think I forgot to respond to Rick that you need a fuel polishing system in any climactic system, unless you empty your tanks and clean them each winter. Ashphaltines will settle out even here in the "Great White North".

Goto: GROCO MARINE PRODUCTS
Select PRODUCTS, then VALVES

#FV65038 sells for $149.95 at:

The one in the picture is exactly the one I found used...it works great.
I agree that if you try and use your return for shifting fuel around you're at risk of over filling a tank....having said that a cross-over at the top of the tank may give a way out for the fuel instead of the vent....but why complicate things.
