How many gallons are these tanks...

[Hopeless Diamond]

Still trying to learn where the gauge reads. Knew I was low, low fuel light never came on (which is weird because I see it flickering sometimes at a qtr tank).

I did feather it though to get as much as possible in, but didn't think I could squeeze in that much.

Wow, 18.4... The most I've ever been able to stuff in my tank, even after running it out of gas once, was 17.7.

Yeah, and I had no sensation that it was starving for fuel at anytime. Was running fine with no hiccups. Pretty sure the filler tube was filled up, although didn't see it all the way up, wasn't at the opening.

I think with a totally topped off filler tube its at 19 or just under as I think I recall when I ran out while coasting to a pump. I guess you're paying a lot more at the pump than us in the northeast, we're paying around $2.50ish on the low end.
