TOPIC: Multiple gas tanks

Is it possible to hook up multiple 6 gallon OMC steel tanks in such a manner that the feed will automatically switch to a full tank as each one empties?

The closest you will come to automatically is if you use an electric fuel switch.
Manual valves are the norm and run about 10 to 15 dollars.

I don't know of any way to have them switch automatically Bill. Could you just get a 12 gal tank to fit the space occupied by the two 6 gal? (Assuming they're side by side or end to end.)

It is possible, but probably not practical. You'd have to have an electronic level sensor for each tank that would feed into a common electronic fuel switch. The sensors would need to be set up so when the reach a certain low level, automatically engages the fuel switch and transfers it to the next tank. It would also have to be an instantaneous switch so the fuel line doesn't loose prime, considering the fuel pump is inside the outboard motor housing.

A 12 gallon tank sounds a whole lot easier.

I answer a way that it can be done on AOMCI "ask a Member

I copy it to here

Yes it can be done...It is realty not automatic and I am not sure if it is USCG approved
We call it the piggy back rig. It will only work with a non auto vent tank....(like the OMC tanks that vent when you plug the line to them)

You install a Fuel Line Connector into the tank top (like on the link below) using a brass backer nut and fiber gasket (and drilling a hole)

You then hook the tank with the new fitting to the motor using the fitting that the factory had on the tank.

You then hook a hose from tank 2 to the tank one using the fitting that you installed.

You leave the vent closed on all but the last tank

We have 3 tanks like this on our duck hunting buggy...We can leave it in the field and bring the tanks home as to fill them...And no pouring gas from a Jerry can to the tank at 4:30 AM... and.....It makes it harder for someone to take the buggy for a joy ride
