i have a question on setting up a smoke oil filling connection. I have a BVM PNP Cougar. The way you fill up the smoke oil tank is to disconnect a festo fitting and pump the oil directly into the tank then reconnect the tubing. It gets pretty tight inside the cockpit and I was wondering if anybody has reengineered a way to refill the smoke oil tank without having to disconnect a festo fitting. I had it come loose during a transport home from a jet meet and dumped smoke oil all over my luggage. I went to Dreamworks site and there’s page after page of different fittings. Thanks for your help
