It doesn't. Or it has a technical stop.

The MAX has a range of 3850 nm, LHR-SFO is 4664 nm

So unless it's an empty ferry flight and you've got very favorable winds, you're not doing that without stopping.

Hawaiian needed extra tanks to ferry their 717 (or was it MD something) over there (there's a picture around IIRC)

Seems obvious once you've seen it...

That was around the time of the merger with McDonnell-Douglas. The 717 was actually the MD-95, so, you're basically correct either way. :)
