That's how I remember it from my 170 days also.
My ragwing had a single outlet, and the fuel lines ran down the forward door posts.
That turned out to be problematic, leading to an engine-driven fuel pump being installed,
so Cessna rerouted the lines down the aft door post in the A & B models but stayed with the single outlet.

"So small hatches".....how small are these small hatches?
Big enough for a standard 5 gallon gas can,
or would it be a bushbag or smaller cans show?

I can’t cite the dimensions, but the openings are narrow, maybe eight or nine inches. Standard five gallon cans don’t fit.

Interesting discussion about usable fuel, etc. My P172D's manual says I have 52 gallon tanks with 42 usable in all configurations, but the manual doesn't say anything about more in straight and level. Flint says, however, that the P172D has 47 usable when flying straight and level. Personally, I prefer not to stretch things. Although I can recall one flight in which the refill took 40.0 gallons, the most I've put in in years has been 37.2, usually right around 37 when I've pushed it a little. That leaves me with about half an hour's usable in all configurations. It also coincides with my usual bladder needs!

I have given some occasional thought to Flints, as I've mentioned. But every time I give it some thought, I decide I'd rather spend the money elsewhere. I just don't have a need for more fuel, just an occasional want. They do look like the best alternative if I did have a need.

I've decided that for my "occasional" aux fuel needs float lockers will work nicely and be functional and offer larger applications as well
