What was found
(CAN) DURING FLT, PILOT NOTICED THE FUEL PRESSURE INDICATION DROP TO ZERO, WITHOUT ANY CHANGE IN ENGINE FUNCTION. THE PILOT CUT SHORT HIS LOCAL FLT, & RETURNED TO THE AIRPORT. THE FUEL PRESSURE TRANSDUCER WAS REPLACED WITH ANOTHER NEW TRANSDUCER, AND THE PRESSURE INDICATION RETURNED TO NORMAL. FURTHER TO THIS, THESE TRANSDUCERS ARE FAILING AT AN ALARMING RATE. EVEN A DISTRIBUTOR OF THESE PRODUCTS ADMITS THAT THEY ARE A DISPOSABLE ITEM.
