Narrative:

Flight attendants reported smelling fuel in aft cabin. Captain took over the conversation with flight attendants and I assumed control of aircraft and radios. I prepared landing data and got set up for the arrival while the captain worked with the flight attendants to resolve where the fuel vapor was coming from. First he had them check the overhead bins where the smell was prevalent. Meanwhile he checked the QRH for smoke/fumes. The checklist is set up mostly for electrical events; so we discussed the steps and decided the ones that would probably help considering we had the fuel leak on the #1 engine. We used those steps to turn the left pack and bleed off. The fumes started to dissipate after that. We then ensured all electrical steps were back on and working; and continued our descent and landed without further event.

Original NASA ASRS Text

Title: B737 flight crew is informed by the flight attendants that there is a fuel smell in the cabin. Since a fuel leak on the number one engine had been detected prior to departure and deemed to be acceptable by Maintenance; the left bleed and pack are shut down and the smell begins to dissipate. The aircraft is taken out of service after landing.
