Id suggest setting up your fuel system properly to begin instead of doing it and
then having to change it all later when its not supply enough fuel for the boost
youll wanna run (as i had to). In the boot set up with appropriate pumps and a
surge tank seems the logical and easiest approach. 2 litre stainless surge tanks
are available from pretty much anywhere in Sydney (star performance for example)
for 100-150 bucks.
