Weird sound coming from rear left wheel well when parked

[Josh Powell]

Does anybody know if this is normal or not? Got home today after driving for about a half hour and walked around my truck while it was still running and heard this odd sound. It's most noticeable inside the driver side rear wheel well. It's kind of like a whining or pumping type of sound. I'll post a link to a video I took. Make sure your volume is up. Thanks.

Sounds like a fuel pump maybe? It seemed to get louder the closer you got to the fuel tank right?

Yea it did get louder closer to the fuel tank. But should it be that loud? I wonder if it's failing, the truck only has 19,000 on it. It's pretty noticeable just walking near the truck while it's running.

Definitely in the tank.

Dumb question, but what is your fuel level?

Did you try shutting the truck off and restarting to see if it goes away?

[Josh Powell]

I believe it's around 3/4 full right now. I rarely ever let it get below a quarter tank and only use top tier. I'm not sure if it does it all the time or only when warm. I just noticed it today. I'm gonna be paying closer attention to it tomo morning and throughout the day. I didn't try to restart it or anything.

If you have a warranty, take it in.

Would hate to see you stranded!

[Josh Powell]

Yea. I have a warranty. Looks like I'm going to have to it in on top of a few other things I need looked at. Was just wondering if anybody else can listen to theirs and see if they if they hear anything like this going on.

Mine makes the noise when you open the drivers door. Pressurizes the fuel system to make it easier to start.

I just walked to my truck after auto starting it from inside my house. I walked up and stuck my head near the gas tank and sure enough it's still doing it. So it's not just when its warmed up.i just don't know if this is normal.

That sounds like a fuel pump going out to me. Unless there’s some kind of emissions pump back there I’m not aware of. Either way I’d take it in.

+1 on the fuel pump failing. My Grand Cherokee did that before the fuel pump failed

[Josh Powell]

Thanks for the responses guys. I've got an appointment to take in next week. Still doing it. Truck seems to be driving fine tho.

There might be something like this living in the tank----------》》》

[Josh Powell]

Maybe

I just bought a 2018 LTZ.  When I go out in the morning and open the drivers door I can hear the fuel pump in the tank kick in and 'prime' the system.  I don't think it would be loud enough to hear with the truck running so I'd agree that yours is about to shoot craps.
