Super Pumper Dual Fuel Pumps
 

Looking thru several 1969/1970 car magazines featuring Motion Corvette articles and I see "Super Pumper" dual electric fuel pumps being used.
Has anyone any knowledge of these?
You usually see the Dupree set-up. I assume Motion may have used different name brand versions and/or individual owners choose what to use.

I think they also used Stewart pumps
