  Mine is this style as a cap and the threaded part is 1 7/8” in diameter.

  Looks like the side fill is the one posted above. That's exactly what I have on my 280. Which apparently has a torn O ring I just discovered as I checked it. 😒

  If you can find a Viton o-ring that fits it will last longer.  If you add some plumbers silicone grease to the oring it helps a lot. They tear from the tightening if they cannot slip a bit. The grease really helps. Over tightening will do it too.
