Mine is a '76 337G; sn 1743 and has the long range tanks (150.6 total; 148 usable.) It has one filler cap on each wing and there are only 3 positions (no aux tanks) on the fuel selector; ON; OFF and XFEED. I believe the owner would know if he has only 93 gallons because it makes an ENORMOUS difference in the feel (heavy weight feel on TO) and the range (when he gets near empty on his guages and fills it - there's no way to miss the extra 55 gallons!!)

As everyone above has said - there's a lot of $$$ difference between the two systems.
