Tom: Since you would have an truly independent system, you could probably use any quality, low-foaming fluid. As far as a reservoir, if you plumb it as two-way or dual-action system (pressure up and down), then you only need a small reservoir to accomodate any fluid loss and/or expansion due to heat during use. If your system doesn't leak, and you check it accurately cold often, you won't need as large a reservoir. If you plumb for single action or one-way, your reservoir will need to big large enough to hold the excess due to heat expansion plus one cylinder in volume. That's why I like double-action. The far side of the cylinder serves as a reservoir of sorts. Now, after all of that, if you had a dual-action system, you could probably get by with a 2 quart reservoir, and only put a quart of fluid in it. Have your cold dipstick marked full at 1 quart, and low at 1/2 quart. That way when you have a full reservoir and it heats up, it will have more than enough volume in the can for the fluid to keep from overflowing. Be sure to use a good breather cap or that reservoir could crush as the fluid inside cools to ambient ! If you want to do it as a single action, then you'll have to add one full displacement of the cylinder to the above SWAG. But I'm truly guessing. A local hydraulic shop can probably give you some better ideas.
