Jay,
This looks like an old one. I preferred to use aluminum tubeing between the header tank and fuel valve and then on to the engine compartment so went in another direction from that valve. Check Aircraft Spruce part number
05-23330
It has threaded fittings you can adapt to barbs and clamps for rubber hose if you prefer or AN flaired fittings for aluminum tubing If that will be your choice.
I would suspect with that valve, if you wanted to change out the tubing periodically, the valve would have to go as well.
