Use the car, put the 12v sprayer in the trunk and extend the wires and 1/2'' fluid line.

Over burden the tank once and you will not enjoy your bath Nor the plastic in your skin.
Since part of my job is dealing with invasive plants, here are some tips:
Mix just enough product that you are gonna use it all and end up with an empty sprayer - product left in the sprayer can lose effectiveness and also really gum up the works.
Clean you're sprayer every time you use it. If you use it for glyphosate (what Round up is) label it as such. I have two sprayers, one strictly for glyphosate and the other for broadleaf killer.
Use indicator dye so you can keep track of where you've been. It will pay for itself in the time and herbicide you save. A little goes a very long way.
Glyphosate typically takes a week or more to show results so don't get discouraged if it looks like nothing is happening. Broadleaf herbicides work differently so the plants show stress much quicker.
This time of year be VERY careful not to spray when it is too warm, especially with broadleaf herbicide. If it evaporates it can drift and take out neighbors' gardens. Grapes are especially fragile. I stop spraying broadleaf herbicide at 75 degrees or so and glyphosate at 80. A light breeze is actually good as it mixes up the air better and lessens the chance of hurting neighboring plants.
For grasses and weeds in berry patches just paint herbicide on with an old rag tied to a stick. Use the same mix as if you were spraying.
Finally, FOLLOW LABEL DIRECTIONS. Monsanto/DOW/BAYER/ORTHO paid people a lot of money to make a product that works, so don't second guess their scientists. Too little of a mix you have poor kill; too hot you burn the tops but don't kill the roots.
Wonder if you could simply drill a hole, get something like these:

Hand pump it first to see what your pressure is at, probably not much. Then use your air compressor on it. I have a low pressure tire gauge for my riding mower tires which is probably what you would use here.
Jacto Inc. - Battery Backpack
jacto makes one that is powered by essentially a power tool battery I have only used their hand pump model and it is hands down the best hand pump model out there the powered version looks like it would work very well and every one I know who has used it have loved it.
I have used all of the commercial pump sprayers and jacto is the only one that doesn't leak on your back.
The plastic ones would probably burst. The metal ones - maybe.
I have a pressure tank that can hold about 150 PSI. I could bring that along to pressurize a metal tank.
So to my question - I assume you've worked with this stuff before. From stuff I've read, the instructions on the containers are generally for big uses, not little uses like mine. Do you know of a mix ratio of the Triclopyr to diesel to surfactant (if that's actually needed)?
How do I know if a herbicide has a clay carrier?
Since you've got some experience with this - mind if I ask a question?
I'm planning to by a version of Triclopyr 4(e) to take care of some woody plants like blackberries. Years ago, a guy I knew did brush clearing for PGE and gave me one pre-mixed bottle of a version of Triclopyr 4 mixed with diesel - it killed blackberries like nothing I had ever seen. He told me not to use a mist type sprayer but the squeeze bottle he gave me had a fine nozzle that would spray a small stream. Just spray that around the base of the blackberries and they'd be brittle, totally dead in a couple of weeks.
We used that up and he no longer works there, so I started looking around and found what he gave me - Garlon aka Triclopyr 4. I found it cheaper with a different brand (Garlon is expensive) - Agri Star. I did a little reading and it looks like mixing it with diesel is a good idea, but some folks recommended a 'surfactant' and a little water. Several also mentioned buying some indicator like you mentioned. So I have all 3 in my cart, but I haven't made the purchase yet, as I want to be sure I have all the right stuff first.

I do understand it can be a bad idea to run this stuff through a regular sprayer since overspray could kill more than you wanted.
Surfactant is product that does the same as diesel only MUCH more environmentally friendly. Basically, its job is to help herbicide stick to whatever you are spraying.
For blackberries you really don't need any, as the leaves are not waxy and liquids stay on them pretty well. Never hurts though and about 2 tablespoons per gallon is fine.
As to the mix, the container should give you the water to herbicide ratio.
Be real careful of drift with that stuff.
Good luck!
Just don't spray 2-4,D when it's hot...
What happens when you do that? Does it off gas and kill plants nearby that weren't sprayed?
