XP3 Air Leak
I've got an API Filstar xp3 with an air leak that I thought I had solved but its back again, and I'm looking for any other solutions out there. The problem is coming from the inlet pipe, specifically I can't get the priming cap to seal correctly and air is leaking in. I had put some Teflon tape around it after having problems when I first got it, and it did fix the issue until today. I've thrown a wine bottle stopper in the priming tube for now, and it does seem to be better than what the cap was doing but I'd like a more permanent solution.
I'm wondering if anyone else has had this problem, and how did they fix it? Also I have come across a couple inlet/outlet tray of accessories that look pretty different than mine and I was wondering if any generation of these parts is better than another.
Thanks for any help you can give!
