I've often wondered why you couldn't put a cross-over line in the bottom of the tanks so they would self level. It works very well on BIG RIG saddle tanks. Seems to me the line could run across the transom and be out of the way.

Just a thought.

stick the damn flag rod in there................

Dont know if its right, but it works for me.

I have both feeds from my tanks going to a T then right to the fuel pump.

Whenever I fill it up, Its almost identical amounts of fuel in each tank.

I spend most of my day just floating around, so i guess once the air is out of the system, they self level..

Just my .02

If you have top feed tanks. If the fuel feed hoses are the same length. Mount the tee lower than the tanks or as low as possible, then to fuel filter and fuel pump. Then they will both feed the same, so only one guage is needed. Personally I just keep a yardstick in the boat and check it manually. Pat

Yes, wooden dowels can be used for many things. I keep a manual fuel guage in my Hallett as well.
How you doing Pat?

the only reson you keep a dowel in the boat is to stir the ice chest to look for another beer so your hand don't get to cold

no, i am saying that if your lines and/or "T", are higher than the fuel level (or if your fuel line connects at the top of the tank and feeds through a tube). then your tanks will not self level...

some people say that if your 2 feed lines running to the "T" are the exact same length then you will draw off both tanks at the exact same rate... for cheap insurance you can install a fuel switch or use a pair of ball valves

like i said, hight school science class. remember?

My boat has two tanks and one guage with a toggle switch on the dash.
Flip the switch to the right it reads the right side and draws from the right side. Flip the switch to the left side it reads the left side and draws from the left side. I just draw from one tank @ a time about a 1/4 tank from each side to keep balance.

The senders are a variable resistor. Two resistors of the same value in parallel will yield half the total resistance. This means that two senders in parallel will yield half the total resistance when both tanks are empty, giving a half full reading. When you fill up one side, one of the senders will have 0 resistance to ground, thereby shorting out the other sender, giving a full indication with only 1 side full.

So you have to hook a SPDT (single pole double throw) toggle switch up to switch the gauge between the two tanks. This type of a switch will have 3 terminals on the backsie of it. The "S" terminal of the gauge goes to the center terminal of the switch. The right tank sender goes to one of the two end terminals of the switch, while the left sender's hot goes to the other end terminal of the switch.
