Default Help festo fitting/smoke system

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

The smoke system in my Boomer is filled up via a separate line with a dot at the end, one thing I make sure when I stop the engine after a flight is to close the smoke and fuel festo valve, if I don't I will be looking at hot start or dripping of smoke oil during the fill up.

I'd just put in a shutoff valve and a tee between the tank and the new valve on the line going to the pump. On the Tee, I'd add on about 10" of tygon tube and use a dot/plug to cap it off. Make that tygon long enough to keep your oiling connection outside of the plane. That way, any oiling spillage is outside the plane. If you want to get fancy, one could use a fuel dot in the fuse and just pull out the oiling line out to fill the tank w/o removing the cockpit/canopy. If one wants to stay scale, install an access door/panel along a panel line and hide the whole thing behind the door. Just a matter of how much work you want to put into it and how scale you want it to be.
