Fuel leak again...
I have a 2020 F-350 6.7. Got fuel leak a few weeks ago and the dealer claimed it's fixed. Now it's leaking fuel again. I'm new to trucks. and have never had fuel leak issues in the past. There are two recalls on this truck (payload sticker and spring seat weld) in additional to the fuel leaks in my first year of ownership. Is it a common issue in Ford trucks?

My GMC had three recalls in the first year and a metallic tapping from the front axle that was never able to be fixed. GM was on the 11th revision of possible fixes when I sold it. Don't think bugs are specific to any one manufacturer.

Fuel leak
I can see the leak coming from behind the fuel system in the valley running between the bell housing and motor to the ground . It only happens when it's parked and makes about a 9 in puddle , I appreciate any help I can get thanks guys

I'm surprised you only see it when parked. I would expect any leak under the hood to be spraying.

Your leak is most likely coming from the "Fuel/Water" drain. The O-rings have shrunk due to the cold and fuel is leaking into the valley instead of going down the drain tube. Easy fix if that is where your leak is. Ask and we will tell you what to do. The leak only happens when parked because the pressure/fuel that is in the fuel bowl in bleeding out the drain valve area.

You are in the 'SuperDuty' thread (which your truck is a SuperDuty). Go to the 1999-2003 Diesel thread that is open.
If your fuel leak is the Fuel Bowl lid, that is one issue.
If your fuel leak is the Drain Valve, that is another issue.
