## Discrepancy

WHILE PERFORMING A PRESSURE TEST OF THE EXHAUST IAW AD 71-09-07, NOTED EXCESSIVE LEAK AT THE CLAMP AFT OF THE NR 2 CYLINDER BELOW THE ALTERNATOR AND ENGINE DRIVEN FUEL PUMP.  ONCE THE CLAMP WAS REMOVED, IT WAS NOTED THAT BOTH EXHAUST PIPES WERE THE SAME SIZE AND WOULD NOT SLIP-FIT INTO EACH OTHER.  THE PIPES, PN 12508690-90, AND THE KNISLEY FAA-PMA'ED PIPE, PN K1250860-203, WERE NEVER INSTALLED CORRECTLY AND THE EXHAUST LEAK WAS BLOWING DIRECTLY ON THE ENGINE DRIVEN FUEL PUMP.  THIS WAS NOTED BY THE ANEROID HOUSING BEING STAINED BY THE EXHAUST.
