GEN 2 Loud scraping noise from front undercarriage upon acceleration

[edouglas30]

I have a 2018 Raptor I've been hearing that noise on my truck like if something is in my bed and hits the wall been ignoring it for maybe about 7 months but today I herd it loud like a tire exploded , and it does usually happen when I finish pumping gas. Have you found out what it is?

I have had 17 and 19 and they both do this after pumping gas. It has to do with where the vent is at for the fuel tank. When you fill it up and the pump clicks off don't fill it anymore and it won't be as bad. Weird thing is it does it worse with higher octane fuel. If I fill with 87 octane it won't do it unless I fill it to the top after pump clicks off. Hope this helps
