One of the banes of my existence has been the filler neck on the Exocet. I’ve been through a bunch of iterations. The first sent gas shooting back up at me, the 2nd involved an expensive 3d printed elbow but always clicked off too early and a filler door that didn’t fully close. Tonight I got my latest part in the mail (an ultra-flexible gas filler neck tube). After some cutting, testing, then cutting some more - I have a gas filler and fuel door that fully closes. It also looks pretty clean (except for the dust in the photo).
