For the project race car, the fuel cell has been located directly under and up against the rear floor so the filler hose has to come in through the rear quarter panel above the floor into the top of the cell. Is there any simple way to clad it, as far as I know there is no suitable off the shelf clad hose available. For venting I'm assuming that braided stainless fuel line will be OK.
There is a good reason for mounting the cell up against the floor, that's not going to be changed. So, solution?
