[s-cars] Scotty to Captain Kirk, "I'm givin yah all I've got Capn"

Hap:

I don't understand the fuel return visiting the reservoir.  How/Why?

I would have expected the reservoir to be under the same pressure as the
fuel rail.   The return line is at a much lower pressure, since it is
downstream of the pressure regulator.  If you were to tap the return line
into the reservoir, then wouldn't you just be short circuiting the fuel rail
and be pumping the pressurized fuel right back into the tank?   And under
the sustained WOT conditions with big injectors that might exceed the
capacity of the fuel rail and necessitate the reservoir, I'd imagine there
would be insufficient fuel pressure at the regulator to cause it to open and
bleed fuel back to the tank anyway.

Its being fed by the stock pump at that pump's max rate. In addition the 
return from the fuel rail pays a visit to the reservoir before heading back
to the 
fuel tank. The amount of fuel in the reservoir is more than sufficient to 
handle all track and quarter mile duties according to my CU Engineering
School 
grads.
