William,
You really don't need all those fancy plumbing attachments.
You can make a compression fitting by simply drilling a 3/16" hole into your 50 gallon bucket and sticking a
1/4" drip line into it.
I've done this many times, never leaked.

Just checked this link again.

To connect the 1/4" inch tubing to the 55 gallon container, I simply drilled a hole (forgot what size, but less then 1/4"), then took a big spike nail and rotated it in the hole. This made the hole taper in (?), then cut the 1/4" tubing at an angle and forced it in. Works great, no leaking and very simple. Definitely recommend practicing on some other plastic containers first though before drilling the 55 gallon one.
