You need safety glasses, an air compressor, hose, blow gun with rubber tip, a length or poly tubing (I used 3/16” ID cuz it was what I had), electrical tape and of course the bottle of fluid you are putting in.
I cut a hole on the bottle lid tight enough so the tubing is real snug (cap removed from bottle). Pull the hose through the cap leaving enough to reach the bottom of the bottle on the one side and enough to comfortably reach what I’m servicing. Wrap electrical tape around the bottle side tubing thick enough to form a seal when you pull out slightly on the tube and then wrap the outside of the tune so it stays in place. I cut the bottom of the tube at a slight angle to ensure flow. Install the tube and cap on the bottle, poke a hole near the top of the bottle above the fluid level, put free end of hose into the fill hole of what you are servicing. **** with LOW PRESSURE (10-25psi) !!!! press the rubber tip of the blow gun to the hole and SLOWLY apply air to the bottle. I’m wearing safety glasses because there is a pressurized vessel of fluid that is not designed to be pressurized in front of my face. But I can watch the fluid go up the hose into the fill hole and easily see when it is full. I’ve used transfer pumps before and it only takes 3 pumps (just like it takes 3 licks to get to the center of a tootsie pop) but I find this easier. Hope it helps someone. If you hate the idea and find it utterly ridiculous, it’s ok. Let me know and Don’t use it. I won’t be hurt.
