Flybox Omnia Fuel P (57 mm & 80 mm)
The Flybox Omnia Fuel P is a dedicated aircraft fuel delivery pressure gauge engineered for Ultralight, Light Sport (LSA), and Experimental aircraft. Designed to monitor fuel feed circuits across carburetted and injected engines, it pairs a crisp graphical dial with bold digital readouts and customisable colour arcs in either Bar or PSI. Compatible with 0.5–4.5 V analogue pressure transducers and direct engine CAN-bus data (Rotax 912iS/915iS and ULPower). Available in standard 57 mm (2-1/4″) and 80 mm (3-1/8″) round panel cutouts.
Choosing Your Instrument Size
Select the standard round aviation cutout diameter suited to your cockpit panel arrangement:
Omnia57 Fuel P (57 mm / 2-1/4″)
The compact choice for space-constrained panels, centre pedestals, or secondary consoles. Features a 68.5 mm × 62.0 mm outer bezel, weighing only 140 g with a low 60 mA power draw. Fits standard 57 mm cutouts (57.5 mm recommended) with up to 10 mm internal screw depth.
Omnia80 Fuel P (80 mm / 3-1/8″)
The direct drop-in replacement for traditional 3-1/8″ round mechanical fuel pressure gauges. Features an 84.0 mm × 84.0 mm square bezel and expanded 3.5″ display area for primary flight scanning. Fits standard 80 mm cutouts (80.5 mm recommended) using M4×6mm screws (maximum 3.5 mm internal screw thread depth).
Operational Capabilities & Fuel Circuit Safety
Precision fluid pressure tracking engineered to protect your engine from fuel delivery anomalies:
Dedicated Pressure Dial
Presents continuous fuel delivery line pressure using a high-visibility circular colour scale and large digital numbers. User-selectable between Bar and PSI to match your aircraft Pilot Operating Handbook (POH).
Custom Operational Arcs
Easily program low red (starvation limit), low yellow (caution), green (normal operating), high yellow, and high red (overpressure limit) bands directly via the intuitive rotary encoder knob.
Analogue & CAN-Bus Sources
Accepts standard 0.5–4.5 V transducers (Flybox 601041, Kavlico 15 PSI, or generic senders with custom full-scale settings) and reads digital engine CAN-bus data directly from Rotax 912iS/915iS and ULPower powerplants.
Dual Alarms & Delay Timers
Features independent high and low visual warning banners and an NPN open-collector alarm output (300 mA). Includes programmable activation delay timers (0 to 10 seconds) to eliminate nuisance alarms during transient pump priming.
