Even after 30 years I continue to learn something new every day! I had not seen the VG3 nor any reference to it before, and I've talked with a lot of VF owners! Thanks for
posting it...I'll add it to my files.
If space saving was the reason for combining the vac tank and
pump into a compact "generator," the VG3 doesn't appear to be any improvement on the original separate vac tank and
pump that could spaced far enough apart to provide easy access to 'em. Is it still in production, or one of those things seemed like a good idea but turned out not to be?
