Mike, it's generally accepted that Saitos use 1 oz of fuel per minute, per minute, per cubic inch of displacement, at full throttle. This rule is not iron clad as the larger the engine the better the fuel economy is. So 1.15 x 10, (minutes) would equal about 11.5 oz. The low speed needle has a huge effect on this. I mostly use Roto Flow tanks, the one on my PSP test stand is a 14 oz which fits the bracket perfectly. All the plumbing inside is metal.
