Based on what you said, I think you are safe to continue driving your vehicle. I would guess that there is a small vapor leak that may have occurred while replacing the fuel pump. Sort of like leaving your gas cap loose. The EPA doesn't like gas vapors but not to worry. The only concern is the engine light being on for THIS issue, may conceal a different problem that comes up later. So just scan your codes once a week to see if anything different is happening that needs immediate attention. You're good.
