## Discrepancy

(CAN) THE ACFT DEVELOPED A ROUGH RUNNING ENGINE IN FLIGHT.  ONE OF THE ISSUES WAS A LEAKY EXHAUST VALVE.  DURING SETUP OF THE ENGINE AFTER REPAIRS, IT WAS FOUND THAT WHILE THE SID 3-7F FUEL SETUP WAS COMPLETED THE MECHANIC COULD NOT GET ANY INDICATION OUT OF THE LOW PRESSURE SIDE OF THE ELECTRIC FUEL PUMP.  THE HIGH PRESSURE OR PRIMING SIDE WAS WORKING NORMALLY.
