Little help with a fuel line please.

[Zonaman]

I've got a '69 half ton that needs a new fuel tank sending unit. I want to install the unit for a '72 because I've heard the vent line can be used as a return line if I decide to fuel inject the engine. Problem: The line immidiatelly following the unit connects with a flair nut and the '72 looks to be couple with hose & clamps. I don't seem to be able to find just that segment of the fuel line from the sender to under the cab floor that fastens with hose and clamps. Can that be ordered anywhere or do I just get some tubing off the shelf and bend it?

Thanks.
