52Carl,
Just to clearify. "half-barrel sized beer keg"? Are you saying a real beer keg? = U.S. brewers sell beer in .5 barrels of 15.5 gallons?
Just to clarify, I am mostly full of crap. However I would not be surprised if the volume needed would be larger than the big soup can-sized reservoirs. For whatever reason, these 6 cylinders, at highway speed, don't make enough vacuum to run the wipers. So unless you are allowing the throttle to close from time to time while you are cruising on the highway, you will run out of vacuum in the reservoir. (Now that sounds stupid. Vacuum is the absence of air, so how do you run out of what was never there?)
