[Diy_efi] Supra Transfer Fuel Pump

[Toyota Supra]

hey scott, this was attempted, it was too much of a restriction and put base 
pressure way to high. i thought about trying to build another venturi valve, 
but i don't have the proper equipment to test it out, and i don't want to 
find out the hard way by having to run out of gas. besides that it takes 3 
hours to R&R the tank, so i only want to do this once.
