I don't have a Ford (as indicated by my sig) but I've heard a similar noise from the rear of my coach at times.

I believe it's the in-tank fuel pump. I have a 75 gallon tank that can act as an amplifier and I'm guessing that at certain fuel levels it amplifies the natural fuel pump frequency.

Of course if my fuel pump dies an unexpected death in the coming days, please disregard my thoughts on the matter.

I just worked on a 2011 22000LBS chassis and I don't remember the pump being that loud. I would compare it to another 2011 myself and come armed with that info if the pump is excessively loud. Fuel pump issues are not common by any means but it can happen.
The video is a good representation of the sound. I don't have to get under there to hear it. I can stand at the back of the coach and can hear it. I talked to another guy on these forums who own the same coach and he does not have that sound. So what are you guys' consensus? Should I take this to the dealer and have them replace it? We only got the thing on Friday. You think they should replace it at no charge? And is this something covered under warranty? I'll have to go through the book today.

I've only heard it a couple of times so I don't really know. That's why I think it's related to how much fuel is in the tank. At a certain level it may be resonating and amplifying the sound of the electric fuel pump. A few months ago I heard it really singing when I stood at the back of the coach with the engine idling. Haven't heard it since then. I've put about 500 miles on it since I last heard the sound.

Was that when your fuel tank was full/nearly full?

I have no insight into what may be causing the problem, but if it bothers you (and clearly it does) you should definately take it back to the dealer. You indicated that you have only had it for a few days. I suspect that since it is a 2011 model that you are a second owner? I would think that any reputable dealer would work with you to solve the issue, especially being so soon after the sale.

Please post back whatever the resolution is to keep us all informed.

At our dealership it was loud with some motorhomes and quieter on the same chassis with anouther. Our ford Rep. said they had investigated and found there were no higher failure rates on the loud ones. They investigated and found some part of the pump and arm assy. was touching the tank and causing the higher noise level. I would not worry about it.

Well that makes me a feel a little better. I called the dealership today - our sales guy wasn't in and neither was the service manager so I'll have to call back tomorrow.

I believe the fuel pump is covered under 3/36, I don't believe it is under the 5/60 warranty but may be. If the noise is excessive when compared to other like units, then it would be warrantable. Some pumps are naturally louder than others with no reliability issues.

It was nearly full at the time. Since then I've listened with it full and haven't heard it.

I think you're right, james. Looking on the web it appears that is is covered under the powertrain 5/60 by Ford. I'll take a more detailed look at my warranty book when I get back home.

I just wanted to say that I just had some of the best customer service from Ford. Ford has there own motorhome hotline for the chassis and the woman there was super friendly and helpful and Dan at Hampton Ford up here in NH was extremely helpful and friendly as well! So many times company's "customer service" is anything but, with people sounding more like they're annoyed that you called. This was certainly a pleasure!

Brought the thing to Ford. They replaced the pump. Sound is still there :( Oh well. Guess I'll just have to deal with it.

I dd an experiment today. My fuel tank was ~1/2 full. With the engine idling I walked to the rear of the coach and I could hear the fuel pump singing as I stood behind the trailer hitch area.

I drove the gas station and filled the tank. When I returned home I walked behind the coach with the engine idling. I couldn't hear the fuel pump until I bent down below the trailer hitch and cocked my ear towards the tank - I could hear it then but only faintly.

This seems to support my theory of the tank amplifying the sound when it has a certain amount of air space above the fuel level. I'm not going to worry about it.
