Adding Second Fuel Tank, What Will Fit?
I am about to add a second fuel tank (I have a 6 and will add a 12-gallon tank).
Moeller has two on the market: tall profile at 14" W x 23" L x 14.5" H & low profile at 18" W x 24" L x 11.5" H.
The boat is 90 miles away so I can't measure the space myself. Which one would fit the best on a 2006
?

Not sure about the moeller's but some one will know. I have tempo tanks.
I do like moeller's gas gauge and cap better than the tempo's.
The tempo measures 14 1/4 high to the top of the cap. and it fits just fine.
make sure when sailing and the tank is full that you close the vent. It will spill fuel a little while heeling and stinks up the cockpit. Then when getting ready to motor the vent is open again. Or you will "just ask mike" about how bad the engine is running and stalls with the new tank.
If you do get the Moeller please let me know if you like it. I want to change to them because of the cap and vent they have.

I have 2 of the 12 gal Tempo's. You can see how they fit here...

I would also add that the vents should be left open when left on the boat. The heat from the sun is enough to make those rectangular tanks turn into nice round balloons without venting the air inside.make sure when sailing and the tank is full that you close the vent.

Yeah, did that this spring! Had both tanks empty and vents closed. Just enough residual fumes to make the tanks swell so tight that I couldn't even run my skinny hand across the top of the tank to reach the cap / vent. Had to wait till middle of the night when temp cooled down enough to open the vents!The heat from the sun is enough to make those rectangular tanks turn into nice round balloons without venting the air inside.

Fuel Tank Report
I bought the standard Moeller 12-gallon tank. It has a total height of 14.5" & width of 14". Got it to the boat and discovered that the space available under the seat was roughly 11.5 inches on my `06 model 26M. Back to WM and ordered the low-profile version (supposed to be 11.5" tall but is 18" wide). The Moeller 12-gallon low-profile fits quite well in the compartment. The cap/hose connector are just a hair taller than the available vertical space so the compartment cover (seat) sits up about 1/16-1/8 inch on the non-hinged end.
Made the 23 mile passage from Port Washington to Milwaukee at roughly 8-10 mph into a 15 knot headwind & 2-4 foot rollers using just under 5 gallons of gas. Now I know first hand about the spray that comes back into the cockpit with those wind/wave conditions.

I have the 12 gallon tanks sitting in the garage and replaced them with 6 gallon Temo tanks. I like the idea of being able to easily take the tank out, put it in the back of the Trailblazer and filling it at the local gas stop (cheaper).
Of course, I am lucky if I use 5 gallons of gas a sailing season so big tanks are not useful to me.

Calling Mike (or anyone else who can help).....................................
Two problems:
1. Got a replacement masthead unit for my ST50 wind/close hauled instrument from ebay. Trouble is that it turns out not to an ST50 masthead unit at all, but a VDO unit. Is there any way that I get the signals from the VDO to be read by the ST50?
2. Installed a plastimo 100 litre flexible water tank under the front bunk on the weekend. Plumbed it to the galley sink, and to the dunny (head) sink via a 'T' just after the tank outlet. Installed basic in-line one-way valves a couple of foot from each faucet to keep the lines full. The faucets that I have are Trojan plunger type. The one in the dunny works fine, but the galley unit locks at the top of the upstroke after about five pumps and then takes some jiggling before it will go down again. After that, it sticks each time. Leave it for five minutes and I get five pumps before locking again.
I'm wondering if it is the in-line one-way valve. They are not the flapper type, but rather a basic loose ball type. It occurs to me that it might be sealing at the end of the upstroke and preventing the downstroke from exerting positive pressure, but that is a guess. I can remove them to see if the problem goes away, but thought that there may be something else that I have forgotten somewhere.
Doctor......................tell me............................is there any hope???????????????
