best practice first, clean up all the diesel then turn your truck on and observe exactly where the leak is coming from. replacement is the easy job

I wish we can see exactly which line your referring too

Are you sure both are leaking? That’s weird.

yes coming from the bottom where it’s connected to the pump maybe the seal.
