If you own a Debonair, certainly you will be interested in what
Wing Tip Tanks can do for you. Not only extended range but a gross weight
allowance increase as well. Even on a short flight, point A to point B and
returning without having to take precious time to refuel at point B. Not to
mention the fuel savings when topping off with low priced fuel. Increased engine
and airframe life due to fewer take offs and landings while not having to stop
for fuel.
J. L. Osborne, Inc. formerly Brittain Industries, pioneered the
development of wing tip tanks for civilian aircraft many years
ago. Completely developing and redesigning the aluminum wing tip
tank (20 gallons each) for the Bonanza, Navion, and Twin Navion,
also the Single and Twin Piper Comanche's (15 gallon each). The
20-gallon wing tip tank is streamlined and smooth, with recessed
Nav/Strobe lights, a flush filler and concealed drain. By means
of drop hammer dies, the shells are formed of heat treated
aluminum which is hardened to resist dents and distortion. The
tank is assembled with flush welds, eliminating any raw edges or
flanges protruding into the line of flight. We consider this
tank aesthetically and aerodynamically outstanding. Together
with this Tip Tank design, several installation hardware kits
for different models make system installation practical.
DIRECT FEED SYSTEM
Salient features of the installation are simplicity of the
 mounting
of the tank which requires no rework of the wing whatsoever.
Fuel lines are readily routed through the existing rib holes in
the wind structure. The fuel system being a direct feed,
consisting of a manually operated five-position selector valve,
including a Tip Tank “cross-feed” capability. A separate
selector valve system is available for earlier models, working
in conjunction with the factory selector valve system.
TRANSFER SYSTEM
Fuel lines are readily routed forward of the main wing spar
connecting to a Transfer
Pump/Flow Switch Assembly. The Transfer Pump/Flow Switch
Assembly is located near the forward wing inspection cover,
accommodating pump filter installation ease, maintenance, etc..
Other options include manual turn off when a desired amount of
fuel has been transferred. After the Tip Tank fuel transfer is
initiated (tip transfer pump) tip fuel enters the corresponding
main tank through its' factory metal (bladder) inspection cover;
leaving no fuel line installation holes in the main tank
bladder. This transfer system transfers fuel by an electric pump
turning off automatically when Tip Tanks empty.
