Narrative:
[I] took turn over from 3rd shift for a fuel pump module (fpmu) carbon seal change on right-hand engine of an emb-145 aircraft for oil leaking from carbon seal of fpmu. When I arrived at the right-hand engine noticed; #2 generator sight glass [was] full of oil and noted discrepancy on a non-routine write-up card. Followed procedure for remove and replace of generator carbon seal; then noticed hydraulic pump had evidence of leakage; noted discrepancy on another non-routine write-up card.was in process of removing and replacing the hydraulic pump and was approached by a federal agency inspector who asked for my paperwork for the removal and replacement of the hydraulic pump. The inspector asked me if I had pulled the circuit breaker for the removal and replacement of the hydraulic pump. At that time I said I had; was not sure; because I remembered pulling a circuit breaker for the removal and replacement of the generator but not for the hydraulic pump. Inspector went and looked and when he returned I told him that I hadn't and was in process of going to cockpit to collar proper circuit breaker as required. I did not follow established procedures for the removal and replacement of the hydraulic pump change. When multitasking several remove and replace items; be sure to follow established procedures for each event. Also double-check between each task.
