Narrative:

There was a strong smell of what might have been fuel from push back. It continued into the flight for the duration of the flight. The odor was in the aft galley. A non-rev pilot went to the aft galley and he also said he smelled the odor. This was related to the captain and they thought there might be a fuel leak that was pooling and could cause a fire. The captain decided to land in ZZZ. I believe he shut one of the fuel lines. The odor dissipated. The mechanics came aboard and checked all possibilities. No leak was found and after about 3 hours when the mechanics were satisfied -- we continued on. I was working the first class cabin but did go to the back galley during the flight and the odor was strong.
