Hi armchair,
In your already mentioning cleaning out your sediment bowl once, combined with mentioning the prior 10-12 years of having an idle 80+ year old gas tank not used often, there is still a "possibility" that when you continue your initial daily sloshing around of new gas in an old tank that old stale fuel sludge & varnish combined with rust flakes & debris could plug your shut off valve & cause your engine to just completely die on the highway.
The most dangerous part is that if your vintage vehicle "possibly" dies on today's highway, today's modern texting vehicle drivers are not at all used to seeing a completely stopped car on the highway.
Just for your life safety, & that of passengers, you may want to consider providing an "in-tank-screen" at the fuel shut off valve -- it will not hurt performance, but can give you peace of mind -- today's 18 wheelers or faster moving vehicles can hit very hard.
Just hope this can help anyone getting out on the highway in today's traffic with a vintage vehicle that was stored & not used often.
Just a few actual experiences to share.
