Bob,
That is what I implied by "Creative Plumbing"
In my 2009 rule book under 1:5 Gen Regs FUEL SYSTEM Pumps/Valves the last line says: All cars in Stock, Super Stock, Comp & Pro stock must be equipped with a positive-lock drain valve located between the fuel tank and the carburetor(s) or fuel injection to facilitate removal of fuel samples for fuel-check purposes.
The way I read that the fuel sample valve doesn't have to be on the pressure side of the pump. It could be gravity feed from the line going into the pump.
Just my .02
