Hi,
Hubby was a Cummins Diesel instructor for 35+ years. I just read him your post.
He recalls that the Dodge fuel tanks have a baffle to prevent people from siphoning fuel... BUT.. if you can get the hose in and well connected (as you stated) it could just work to get you to a dealer.
HOWEVER, there are certainly some concerns ATTEMPING THIS as it is a SAFETY ISSUE and you are taking some risks with this repair. Also, technically it's illegal to run like this, but it sounds like you're stuck and just limping in.
Good luck...
