## Discrepancy

AFTER A REBUILT TCM ENGINE WAS INSTALLED INTO THIS AIRFRAME A SECOND REBUILT ABSOLUTE PRESSURE RELIEF VALVE FROM CONSOLIDATED FUEL SYSTEMS, INC. WAS INSTALLED AND THE ENGINE WOULD NOT PRODUCE 36.5 IN OF MANIFOLD PRESSURE REQUIRED FOR TAKEOFF. REINSTALLED THE ORIGINAL RELIEF VALVE AND THE ENGINE PRODUCED 36.5 IN OF MANIFOLD PRESSURE.
