fuel pump continues to run

After I turn off the motor the fuel pump keeps running for another 15 to 20 seconds. Any idea why? Thanks in advance!

This must be "Fuel Pump Week" here at TGO. We've had several of these in the past few days.

Yes, it can be completely normal. You can search the archives and find a lot of explanation.
