The connection from the tank to the fuel box unit (FBU) must be made with a single direct
hose, with an optimal length to minimize pressure drops along the line but without creating
any tension or bending of the pipes along the line.
Bending on the fuel line can cause the engine shutdown during the flight or fuel leakage
due to an excessive overpressure.
Use the transparent 6.4 x 3.2 mm Tygon Saint Gobain LP-1200 tube supplied by Vittorazi for
the supply and the return lines. This will allow:
•
When the main switch is turned on, to see fuel entering in the FBU.
•
With the engine running, to notice possible bubbles due to the air aspiration in the
fuel line. In this case, carefully check the pipe connections.
