The entire fuel line must be airtight. Entry of air into the line can cause irregular system
operation or even the engine shutdown during the flight.
The position of the tank and the configuration of the fuel line could affect the operation of
the EFI system and the engine. Vittorazi has performed many validation tests to identify the
right configuration and its limits.
The optimal distance between the bottom of the tank and the FBU inlet to ensure proper
engine operation is 40 ± 15 cms. A different distance may generate a variation in fuel flow
rate, compromising the performance of the EFI system and creating a risk of engine
overheating.
In case this value cannot be respected due to particular aircraft geometries, contact Vittorazi
directly.
