## Discrepancy

(CAN) UPON DISCONNECTING COMPONENTS TO REMOVE THE CENTER SECTION BLADDERS, SOME COMPONENTS WERE FOUND TO BE CONNECTED INCORRECTLY.  UPON CONSULTING MM TO VERIFY WIRING, FOUND THE FOLLOWING: THE RT ENGINE FUEL LINE WAS CONNECTED TO THE LT FUEL SHUTOFF AND THE RT FUEL BOOST PUMP.  THE LT ENGINE FUEL LINE WAS CONNECTED TO THE RT FUEL SHUTOFF AND THE LT FUEL BOOST PUMP.  THE FUEL LINES WERE SWAPPED UPON PREVIOUS INSTALLATION AND THE BOOST PUMP WIRING WAS SWAPPED. THIS IS EVIDENCE THAT A FIX FOR THE PROBLEM WAS PREVIOUSLY MADE WITH SWAMPING THE WIRING TO MAKE THE SYS FUNCTION NORMALLY.  HOWEVER THE TRUE ROOT CAUSE WAS NOT DISCOVERED IN THAT THE FUEL SYS PLUMBING ERROR WAS NOT RECTIFIED.
