Making/Buying Small Outboard Gas Tank

[YuccaFlatsRanch]

I recently purchased a 4 HP Evinrude Outboard motor for my 12 foot Foldcat boat. It comes with a 3 1/2 gallon tank, but for most of the time I want a much smaller tank, something around a gallon (less weight and less space) would work fine for a full days fishing. Haven't been able to find one - How would you make one??

Your current 3 1/2 gal tank should have the suction tube and the fitting for the gas line and squeeze bulb.. Why not just take it out of the tank and install it on a gallon sized polyethylene tank. Drill a hole, use some silicone rubber cement for a seal, cut the suction tube down to size, and there you go. Or, maybe find a replacement tube, etc, at a marina and do the same thing.

I need to check the tank when it gets here and see if the fill valve has a pressure relief screw on it. If not I would be good to go with what you indicated.

How about a old lawnmower gas tank, should have fittings already just attach the hose.

We used to go to Canada in the 60's using Pappy's two old 'Elgin' outboards from the 40's. That was Sears b/4 they signed up Ted Williams. Both had the gas tanks built in and re-fueling was a royal pain as we had to carry this large [galvanized] funnel and a 5 gal gas can.

On the otherhand; mounting a small tank would suit your need; especially if you can't go miles away like we did in Canada. Filling the little tank at the dock shouldn't be much of a hassle....
