On 9-14-90 at 2330 CDT, DG 2B was started to perform .a Hot Web Deflection Test-in order to obtain thermodynamic performance' data prior to its scheduled overhaul. At 0410 CDT on 9-15-90, a fuel-line was.found ta be leaking and a conservative decision was made to stop,the-test and                i investigate the leak. At 0412 CDT, the DG was stopped and a. Limiting Contiition for Operation.was entered. -Personnel found that the fuel line        i tubing was mounted at an angle through one ofEits, supports and had cracked where it made contact with an edge of the' support.. A temporary-repair was made and the testing was completed. 2Dur,ing the-ensuing-overhaul, new tubing was installed which was' bentfappropriately as it:           ,
passed through its support mounting to preventaa' recurrence of the              '
cracked line. A check of the other DG ' fuel lines found no other. similar-    .;
