It's a niggle and not arguing against your finely-laid point, but water weighs 8.35 lbs/gal. It's roughly 33% heavier than the fuels these planes used. 50 gallons of water weighs around 420 lbs. That's very significant in the era we're talking.
Fixed!

To follow on the weight of liquids:
One gallon of Gasoline (Petrol) weighs 7.35 pounds.
One gallon of straight coolant weighs 9.3 pounds.
One gallon of SAE 30 motor oil weighs about 7.4 pounds.

One gallon of Jet A weighs 6.6lbs (approximately). In pilot training we used 6.5lbs a gallon (assume it was close enough).

Yeah, we were trained for JP-4 = 6.3 lbs/gal.
I think that's what we used fuel wise in the late 80s early 90s. Somewhere along the way it turned into JP-8 / F-34.

Back when I was a lad, this was a JP4 (Jet Provost T Mk 4):
It was also known as the "constant speed, variable noise machine".

Right, my knowledge on fuels is obsolete as they changed terminology and probably composition in the interim. JP-4 was, as you well know, the standard fuel of that era. The only other fuel I really remember was JP-7 (used in the SR-71, I never had to deal with it as a firedog 'cause we had no -71s) due to its nonvolatility requiring some nasty stuff for ignition.
I don't know the differences in chemical properties between the older fuels and modern booze.

As opposed to a Tweet, which was a variable-speed, constant noise machine!
Goddamned things sounded like a power-drill running at 130 dBs.

I didn't care how it looked, but the Tweetybird taught me to use ear-protection.

I'm a rock-n-roll guitarist and had already played plenty of gigs when I encountered that thing. I never plugged up for a gig.
I plugged up for that little bastard.

I like the way it looks unlike the JP 4

I believe those JP4s saw some decent service in the Mideast.
