## Discrepancy

WHEN LEFT FWD PUMP IS TURNED ON, LEFT AFT FUEL PUMP PRESS LOW LIGHT EXTINGUISH WITH LEFT AFT FUEL PUMP SWITCH OFF.  PULLED VARIOUS CB'S CONFIGUATIONS, STILL SAME EFFECT.  VERFIED HEARING BOTH LEFT FWD AND AFT PUMP RUNNING.  REPLACED O-RINGS ON LT FWD FUEL PUMP.  OP CK AND LK CHECKED PUMP AND PRESSURE SWITCH, OKAY.
