funnel trick

I did a similar trick to do the exact same thing in the lifter valley this past summer. Except for instead of a funnel I used a variety of electrical and plumbing fittings that was laying around to make a more permanent removable hose attachment that necked down to a piece of 3/8” copper tubing that is bent in a curved shape and about 6 or 8 inches long or something…. I will get pics next time I see it. It started with a 1” EMT adapter, then used a 1” NPT to 1/2” NPT pipe coupler and then back to a 1/2” CGB adapter which would normally seal a rubber cork around a piece of electrical wire but I used the copper tubing at this point. It is simple thing to make up and handy as heck, like your funnel.
