Yamaha oil tanks

[dcobbett]

Starting to look for the operational parts for my new Yamaha 130TXRB and I noticed that they have two different sizes of remote oil tanks. Does anyone on the forum know if the larger tank (5 gallons) will fit inside one of the stern seats of a standard 1976 SF and, aside from some obvious advantages (longer time between fill ups, etc.), are there any operational advantages for going with the larger tank?

Also, thinking about adding a fuel management gauge/system, but the Yamaha unit looks very expensive; anyone running another brand unit with their Yamaha, and where there any issues regarding hook up, wiring,operation, etc.
