Vittorazi Moster185 EFI - MI561 - Vittorazi Kraftstoff paper filter

Technische Details

• d. During normal engine operation the electrovalve (16) remains closed, therefore, the injector return line (14) is a static pressurized line. The electrovalve (16) is only opened during the fuel line filling in order to allow the fuel to circulate and remove any air bubbles and in case of overpressure due to fast throttle release. Moster 185 EFI - Installation manual – V1/2024 38 P repare a PUR 5.5 x 8.5 mm tube ( 3 ) for the internal catch tube of the tank with a Vittorazi paper filter ( cod. MI561 ) (2) at the end . Filters other than the original Vittorazi paper filter can compromise the correct functioning of the EFI system by allowing the passage of impurities contained in the fuel that can occlude the fuel line, the components inside the FBU and /or the injector, causing an irregular functioning of the engine, the engine shutdown during the flight or the fuel leakage due to an excessive overpressure. Insert a Vittorazi pass - through ( 4 ) on the other extremity of the catch tube ( 3
