Corbi Air Inc. has upgraded its Billet Fuel Pump. Now outfitted with AN fittings, the upgraded pump addresses a Special Airworthiness Information Bulletin issued June 15 by the FAA on OEM Rotax 912 engines, according to company officials.
The SAIB states: “In some cases, if the input pressure to the mechanical fuel pump is high (e.g., due to an electric fuel pump upstream), the output pressure from the mechanical fuel pump could be excessive. This high fuel pressure may cause the engine to malfunction from flooding and/or cause fuel leakage.” The Billet Fuel Pump resolves this potential problem, Corbi officials said, noting it is immune to inlet overpressure, should the airframe design require an auxiliary pump. The Billet Fuel Pump is powerful enough to do the job alone, unless there is a specific airframe requirement for an auxiliary pump (such as may be necessary to fill a header tank, or for fuel redistribution among tanks in flight), officials add.
Ron Corbi noted that he was about to announce the AN fitting upgrade when the SAIB was issued. “This is a great time to replace the original pump with a Billet Pump, and avoid these kinds of problems forever. If an owner is about to replace a suspicious pump anyway, why not replace it with a better design, a better pump?” Corbi added, “Owners of those ‘SAIB pumps’ have trouble enough. If an owner of an affected engine model places an order for our Billet Pump before Oshkosh, we’ll pay shipping in the continental USA.”
The Billet Fuel Pump is available immediately for $382. For more information: BilletPump.com or 330-337-1180.
