I was sent from Base to ZZZ for a B737-700 aircraft with a #1 Engine fuel leak. We arrived at night. We discovered that the #1 Engine Main Fuel pump was leaking. We inquired about getting an Inspector sent to ZZZ for the fuel pump replacement; but were told by Maintenance Control that no Inspector was required. A fuel pump was sent to ZZZ. The [following] morning; we proceeded to replace the part. I did not see the computer link for the Maintenance Task [Job Card] in Aircraft Maintenance Manual (AMM) 73-11-01/401. I also was not aware that a [specific Job Card] was required. The aircraft was flown on a ferry flight back to Base. Upon my arrival at Base I was told that Job Card was supposed to have been accomplished with the pump replacement. I researched the Maintenance Procedures Manual (MPM) Chapter XX; Table 10.1 and saw that the B737-700 Main Fuel pump replacement was not on the RII list. The aircraft was kept at Base and the Job Card was issued that night during a Routine Overnight Check (RON). The MPM RII list and the Aircraft Maintenance Manual (AMM) reference contradict each other. If Table 10.1 of the MPM doesn't list this job as an RII then why does the Maintenance Manual have a Maintenance Task [Job Card] with an RII requirement? [This was a] failure to use Job Card.
After replacing a Fuel Pump on the #1 Engine of a B737-700; a Line Mechanic was told he should have completed a specific Job Card that included an RII Inspection. Maintenance Control said no inspection was required. Mechanic questions why the Maintenance Procedures Manual (MPM) and the Aircraft Maintenance Manual (AMM) contradict each other.
