Well bought my first ram yesterday and went to put some gas in it and after about the first 2 gallons notice some drops of gas hitting the ground under the truck under the filler, I'm guessing its what looks like a rubber hose going from the filler to the tank and Ive called around but no one seems to sell or list that hose any suggestions? ive found the whole filler assembly online (no hose though)

 

Right after I bought m truck I had to replace the "fuel filler." I had the same problem. When I put gas in it I would notice a leak when pumping. It got worse so I ordered the part which was about $100 or so.

 

If its the rubber hose thats attached to the filler neck thats leaking you can use a radiator hose for the big one and heater hose for the small one. If its the filler neck itself order a new one or look around for a good used one.
