It is one continuous length. You can get a general idea of the routing here:https://packardinfo.com/xoops/html/modules/partslist/viewplate.php?cat=31&partslist=1948-1954&PlateNumber=103A

The original line, being steel, was hard to bend so was undoubtedly preformed and installed on the Left outer frame rail before the body and suspension parts were attached. Replacing it, I suspect you will find it somewhat difficult to lay in a new one piece fuel line in the front where it has intricate bends to thread thru under the L upper A arm and also go across the front crossmemeber under the radiator. It also needs to thread in above and, I believe below, some of the frame outriggers so with the body on that too will be difficult.

Using the more easily bent cupronickel product, it is not as bad but will still require some patience. You can start at the rear end and pull the tubing through most of the route before running into too much difficulty. Being easily bent it will be able to conform to the needed shapes although the final result may not look as pretty as the factory line. Use of a few shorter length commercially available steel pieces would help the situation. The tubing could be purchased in appropriate lengths, bent as needed and arranged so the couplings could be mostly hidden.

The rubber hose between the line and fuel pump is readily available in reproduction. One thing to check is the transition fitting at the end of the hard line where the hose connects below the radiator. If it is a plain inverted flare fitting on the tubing then easy but if it has the older soldered on fitting then that needs to be removed from the old line and transferred to the new.
