2018 F150 5.0 knocking

2018 f150 5.0 has a knocking/ rattling noise coming from under the truck/hood. Bought new in May and it started knocking around September. Only does it while driving and under a load. Around 1500-2000 rpms. It will not do it at idle or running the rpms up while in park. Took it to the dealer a few weeks ago and they said it’s the fuel pump and that all the new ones on the lot do it too. I just have a hard time believing it’s the fuel pump. Can hear it over the a/c and radio. Seems to do it most in 4th and 8th gear. I have a video from in the cab that you can easily hear the noise, I just don’t know how to post it. Anyone have any idea what this may be before I go back to the dealer? Thanks

Tell them to prove you that all vehicle in lot do it. Maybe go on a test drive. That’s BS.
Maybe try a different dealership.
Also you can make a video and post on YouTube and share a link here.
