Fuel / Fuel Care
The
JetCAT P80
can use Jet-A1, 1-K kerosene or deodorized kerosene for fuel. Fuel
must be mixed with 5% synthetic turbine oil.
Example formula:
1 quart of oil in 5 gallons of fuel.
Oil brands like Aeroshell 500 or Exxon 2380 are suitable.
Fuel System
If a header tank is used, the clunk is placed in the main tank. Otherwise, place the
clunk in the last tank before the fuel valve.
Do not use a felt clunk
. The supplied
clunk is designed to reduce the amount of bubbles in the fuel line.
When installing the fuel lines on components with nipples, slightly heat the tubing
before connecting. This will soften the tube, making it easier to install. When installing
tubing on a metal tube, secure the tubing by placing a tie-wrap around the connection.
To remove tubing from nipples, you must cut the tubing off. Be careful not to damage
the nipple when cutting off tubing. To insert tubing into Festo quick release fittings, use
firm pressure until you feel the tube snap in. To release, press in on the front ring, while
pulling the tubing out.
ALWAYS
use a gasoline-compatible stopper. Silicon stoppers swell and leak.
Check your fuel filters every ten (10) flights. You may be surprised how rapidly they can
clog up! The filter is installed with the
O-ring located toward the fuel shut-off valve
.
When running the engine at full power, check the fuel line from the pump to the engine.
If there is a large quantity of air bubbles flowing with the fuel, there is probably a
restriction in the fuel system or an air leak in a fitting.
Hopper Tank
A hopper tank is strongly recommended, between the main fuel tank and the engine.
Using a hopper tank greatly lessens the possibility of air bubbles in the fuel system,
thus reducing the risk of a flameout. The hopper tank should accommodate
approximately two to four (2 to 4) ounces and the fuel pickup should be a brass tube,
positioned in the center of the tank. Do not use a clunk.
