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 had a limited 60-gallon fuel capacity, insufficient for the 250-hp version, prompting the introduction of optional 90-gallon systems and common aftermarket Osborne tip tanks.
- Osborne tip tanks, providing 15 gallons each, were frequently installed on early Comanches (even with the 90-gallon system) and were also a popular addition for Twin Comanches.
- While recent sales of new Osborne systems for Comanches and Navions have been low, the new owners intend to provide continued parts and technical support for existing installations.
