ROTAX 914 FUEL AIR BOX DIFFERENTIAL PRESSURE

These electronic Fuel/Air-box differential pressure gauges and senders are designed for the Rotax 914 engine.  On the 914, the fuel pressure must be measured against the air-box pressure. UMA’s design eliminates having to calculate the fuel/air-box differential pressure by looking at two separate gauges.  Valuable panel space and money are saved by having only one instrument and one sender. These instruments are designed with the 270° sweep, rugged, trouble free, air-core meter movement. These gauges need a UMA N1EU07D differential pressure sender.(below) Installation Instructions
