Maybe a manual water drain valve, and water in fuel sensor.
What part of that has failed? Is it leaking air or fuel? Primer pump doesn't pump or leaks fuel?
If the primer pump is leaking-- maybe you could block it off temporarily?
This right here.
The lift pump is on the hpop, which is separate to what you have pictured. As you've found, new fuel filter housings are backordered. There are individual repair components if something on yours is broken.
BTW, I believe 1873938C95 has been superseded to 1873938C98. Still not available but you might have better luck with that number.
