Um, I think we are talking about 2 different things... the "reservoir" is the vacuum tank that's bolted on the subframe in front of the transmission. Deleting it is as simple as unbolting it and capping the vaccum line that runs to it. Its purpose is to maintain vaccum for the clutch vacuum assist while the car is off. I think wingnut is talking about deleting the vacuum assist altogether, which would make the clutch much heavier (unless your vacuum assist didn't work already, like mine).
