Found: Windshield Wiper Hose for M-38A1

[Grant Bowker]

To clarify - I was working on a CMP, not a M38A1, so the sizing may be different.

I was only trying to suggest a source. If Part Source has it I would guess NAPA (in Queen Charlotte?), Carquest or other auto parts store should also be able to supply. Vacuum line seems to be sized to be 1/32 less ID than the OD of the hard line it is to fit over to ensure a good seal.
Massett is only about 1000 people strong and on an island in Haida Gwaii off the west coast, so Jeep parts may be a challenge for Clint to source. I doubt Massett has a WalMart (or cares about having one), but they likely have at least one mechanical repair outfit who is probably very good at keeping things running because they can't be replaced by going across town to the big box store. It wouldn't surprise me if a repair place of that type either has the line or knows where to find it to keep older equipment running.

Tried Napa and all the local garages, they suggested I scrounge some from an old wreck if I could find one.
