Noticed Tuesday morning the pump was loud. Took it to dealership this morning and they didn't seem to think it was abnormal. Never noticed the noise before especially inside the cab. Was going to have them replace it anyway until they quoted $820. Drained it while ago and fuel looked clean. Anything I should check?
Just filled up Monday night at QT.

Is it your low pressure or high pressure. If it is a low pressure, and you are tuned or de1eted I would do an aftermarket option like fass or airdog or fuellab
