My plans for long runs is to budget about 500ml of fluids per hour. If it’s very hot, maybe more.
I don’t own a vest, but try to filter or refill along the way.
I like hydration belts which carry one or two 500ml bottles.
I don't plan on needing all 3L of fluid for my 3h run either, it's just to get a feel of how it is to run with, I'll only bring the 2L reservoir tomorrow. But I will probably need all 3L for my upcoming 50k.
You don’t plan to stop for water at any aid stations?
You lose a little time to stop and refill, but you also lose time carrying around an extra 4 or 5 pounds of water.
It's self-supported and just me going on a run and not an event, so there aren't any aid stations. I might loop around my home so I do the first 30k in one go and the restock for the last 20k at home.
If you go to the route of carrying all your water, you might try running 6 miles with 3 liters first.
Sometimes I include gas stations or groceries on self-supported routes to refill. Sometimes I buy Gatorade or bring my own Tailwind mix and add it to water. Filtering from natural sources is also an option.
On some solo 50ks I’ve left the house with no water at all, only a plan for how I would acquire it periodically along the way. Without a hydration bladder a hydration belt has been sufficient to carry my gear.

Went on a 25k with the full 3L to get a feel for it, and it felt absolutely fine. No discomfort by the end at all, so hopefully that carries through to the full 50k.
But planning the route along gas stations is not a bad idea, I'll see if there are any close by route I was planning.
