The PUMA FTD has two rear tanks that are approx 26 gallons each. The Puma has a 32 (maybe 33) gallon belly tank (under the seats) w/ an option for one or two 10 gallon rear saddle tanks. It sounds like your 07 Puma was optioned with one 10 gallon rear saddle tank instead of two. I hope this helps. Last edited by rlb8s on May 11th, 2013, 12:04 pm, edited 2 times in total.
