I moved my 18-27 to my house last week and a pickup load of other parts for it...and I found a little round tank that looks like it was bolted to the (from the seat) left side of the stearing colum and to a plate under the gas tank...
The little tank is about 6 inches around and 12 tall...with a glass sediment bowl under and a &quot;gas cap&quot; on the top...
Was this a spare gas tank?
I didnt see where the gas line was tapped into the main line but looks like this is where it goes...
 Thanks
