Fuel System Servicing

After the first 25 hours of operation, then every 50-hours or as
conditions dictate, the fuel filtration screen in the gascolator must be
cleaned. After cleaning, a small amount of grease applied to the
gascolator bowl gasket will facilitate reassembly.
Fuel Requirements
Aviation grade 100 LL (blue) or 100 (green) fuel is the minimum octane
approved for use in this airplane.
Use of lower grades can cause serious engine damage in a
short period. The engine warranty is invalidated by the use of
lower octane fuels.

fillers are located on the forward slope of the wing. Each wing holds a
maximum of 30.3 U.S. gallons. When using less than the standard
60.5-gallon capacity, fuel should be distributed equally between each
side.

Ground fuel nozzle and fuel truck to airplane exhaust pipe and
ground fuel truck or cart to suitable earth ground.
