With some effort, you could have a far superior fuel system at a lower cost. A Walbro 255lph pump is around $130. A quick-fuel low pressure return style regulator is under $80. Add a line to the car and you're all set. These pumps are quiet, and are OEM quality made to last 100,000 miles.
Not a typical approach, but blow-through guys do this with great success.
x2 - I use an an in tank 340 lph pump with return to feed a 580 inch Hemi, so far so good.
