    FX21 questionand can't find it

    2013 FZ21 question. I would like to know the fuel capacity, 2 tanks. Port side seems to run low faster than starboard side. I don't have owners manual and can't find it online.

    Thanks in advance

    I don't know the answer to your question but my 2011 ZX200 tanks do the same thing and a number of other guys have said the same thing as well.

    As stated above. 50 gal. 25 each side. Do to vacuum you will draw fuel faster off one side or the other with the selector set to all/both.

    You should have 2 - 25 gal tanks. I have a 2012 FX21 and I have the choice to draw from either Port, Starboard or Both. Could never get tanks to even remotely draw even when Both was selected. I had the anti flotation valve removed, and while that improved the flow, it still wasn't even enough for me to run it like that. I now run on one tank at a time. My boat has the Yamaha Digital Command gauges, while allow me to monitor fuel flow. Starting with a full tank, it will run out somewhere around 21.3 gals. This amount is exactly what it takes to then fill the tank, even though the book states 25 gal capacity.
