Low fuel - noisy fuel pump

When my fuel is low, I've noticed the fuel pump whines, sometimes pretty loud. While filling the tank up, the whine progressively gets quieter as the fuel level increases.

I can't pinpoint where the whine is coming from, almost sounds like from under the hood.

Has anyone has this happen?

When the fuel level is low and the fuel sloshes around in the tank, it starts to suck up air into the lines. What you hear is actually the lines vibrating.... if you grab the lines on the secondary fuel filter (the one on the engine) while it's doing it you'll be able to feel them vibrating really fast, causing the buzzing sound you hear. Usually cycling the key off and back on takes care of it


Here's the SSM....

"44238 2011-2014 - F-Super Duty - 6.7L - Diesel Fuel Conditioning Module (DFCM) Vibration/Buzzing/Growl
Some 2011-2014 F-Super Duty vehicles equipped with a 6.7L diesel engine may exhibit a vibration/buzz/growl noise from the DFCM and/or low pressure fuel lines. If the noise is experienced when the fuel level is at or below 1/4 tank, this is a normal characteristic and is due to slight amounts of air entering the fuel system during low fuel level conditions. No repairs should be attempted. Fuel system and vehicle durability as well as vehicle drivability and distance to empty (DTE) are not affected. If the noise is occurring with the fuel level above 1/4 tank, follow Pin Point Test MA in the on-line PC/ED to diagnose the low pressure fuel system. The DFCM should not be replaced for audible noises until the fuel filters have been replaced and the system reevaluated.

Thank you Jared for posting this!

Good to see it is normal. I wonder why you don't get noise like this on other types of vehicles?
