This is not quite true, a neighbor of ours years ago raised exotic fish in a 500 gallon aquarium, a aeriator pump was outragously overpriced for the thing so a smog pump driven by a small electric motor worked like a top!! OK on a car they where junk, like the '81 pickup I had with a detonation retarding HEI on it, that piece pinged so dang much with the 305 & smogger heads that you couldn't even get up a hill, tell I yanked it and put a standard HEI in it.
Roger, I restored a '72 SS Chevelle, just at the start of the smog equipment, it actually was ordered without the EGR & smog pump but had 5 lines to the gas tank for venting and recirculating/reburning the fumes, I couldn't find a replacement tank with enough lines coming out so we had to salvage the original! Yeah, real glory days..
