The PA-24 Comanche is a fine airplane, but for the first three years of its production, it held only 60 gallons of fuel, not quite enough for the 250-hp version, which is the reason an extra 30 gallons became available in auxiliary wing tanks by 1961. On the early Comanches, one frequently sees Osborne tip tank installations holding 15 gallons each, and they are sometimes found even when the optional 90-gallon fuel system is installed. The Twin Comanche is also a favorite target for adding wingtip tanks. According to GAMI, very few of the Osborne systems for Navions or Comanches were sold in recent years. The new owners will support existing installations with parts and tech support for as long as possible.

Key Takeaways:
- Early PA-24 Comanches initially had a 60-gallon fuel capacity, which was found insufficient for the 250-hp version, leading to an optional 90-gallon system by 1961.
- Osborne wingtip tanks, adding 15 gallons each, were a common aftermarket solution to extend range for early Comanches and are also popular for Twin Comanches.
- Although few new Osborne systems for Comanches or Navions are sold currently, new owners will continue to provide parts and technical support for existing installations.
