Do you have an adaptor which connects to the upper end to connect a valved adaptor to a 3/4" flanged adaptor to adapt to your mag? Adaptor inception!
It's like I took my entire bin of pneumatic fittings and lego'ed together a 2' extension line.
This contraption of mine came around with me questioning how well silicone oil actually mixes/blends with propane. I was thinking it would be more like oil & water together but it does mix ok and seems to blend in with a little shaking. How I did testing was put oil on top of the ball valve & put a plug over it. Then hook up to propane tank & fill the sight glass resovoir & remove tank. Opening up the ball valve would let the oil run in and I could see what was going on. I dumped & washed out the glass area during my testing. Now when I want to fill oil in gas, I put oil in glass area through ball valve then put tank on inverted and allow propane into glass area. Shake well & stand upright. Most of the time it will all run back into tank. If not, toss tank in freezer for a few min then reconnect and the pressure drop in tank will take it in.
Next trial for me I have some wintergreen oil I'll put in a tank. Then set off a 'nade blank and see how it smells...
