vented gas cap with 2" Fill

dpaliwoda

does anyone have a 2015 Rinker 290 EC. I am trying to find a replacement gas cap. I think it has a 2" fill (the size of the threaded filler hole) and probably made by Perko.  Does any one have a part number or ant information on where I can get a new cap?

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.
