Parked the truck around 10pm last night and then this morning around 7am as I walk by it I hear a humming noise that sounds like an aquarium pump running.

Location of the noise is driver side near back of cab and I'm guessing fuel pump, but why would it be running 9+ hours after turning off truck?

Generally, humming from under the front of the bed of the truck after it has been sitting for some time is the evap pump/system performing an operation. Normal, as long as it stops making the noise eventually.

Appreciate the info, Oats! First time I've heard it in 4 months I've had the truck.
