My RV4 has the older fuel caps with the black o-rings and they need replacing. I asked builder support at vans and was surprised that they could not tell me what size they are so I could order them from another source since they don't carry them. Surprised to find out that they do not know!
I guess I could remove the existing ones and measure them but hoping that one of you has the size handy.
