Looking for ideas on how to route the filler hose through or around the frame to a filler door that will be grafted into the fender. Pictures would be great.

Does anyone know how much clearance there is between the frame rail and the underside of the bed once it's installed (I don't have all the pieces yet or I'd check myself). Wondering I could just squeeze the rubber hose between them or if it would be pinched too much.

It would help tremendously to know what you are working on; make, model, year, etc. We're not mind readers.

On my 49 F1 I mounted a late model Suburban tank under the bed, routed the fuel filler hose between the bed and frame towards the passenger side and used a marine style filler neck in the right rear fender.
On the 48-52 trucks there is approx 1 1/2 to 2 inches between the bedfloor and frame, however you do have to massage the bedside panel a bit as it hangs down below the bed floor.

Ah, that's where I first saw the gas door in the fender. I'm not sure I like notching the frame but it's hard to argue with success.

Well that's disappointing.

I had initially looked at the Mustang tank but I didn't want the fuel filler in the bed floor. Here's a shot of the bed on the truck without a bedfloor, you can see the relation of the frame and the bedsides. I circled the area of the bedfloor that I massaged for clearance of my filler tube.
