well im not sure what to do with the ol' fuel system

um im going to be using the factory injection manifold for a turbo a15 setup, and im not sure what is required for the fuel system

i have a fuel pump off an injected car (volvo of some sort) so i pressume thats a good start, but do i need to use a surge tank or anything like that???, does a fuel injection style pump usually require a high volume pump to feed it?

the injection manifold had an in and return line on it already, another club member is gonna help me out with a larger diametter fuel pump to feed it and i was thinking of using the original for the return line, i guess if i dont use a surge tank i will plumb it into the filler neck (or maybe get tank modified as i prob should put a larger outlet on it anyway)

oh and i now have a spare 14psi holley black pump (used for 1 week around the block a few times only), its the same as the popular holley blue pump except that it has a higher flow rate, anyone interested if i dont need it?
