I would suggest a 3/8" min supply and the same for
the return.. if your going with EFI it will need a
good return.. I myself run a 1/2" supply and return
with my set up.. it was carbed but now I run a Holley
multi point EFI and the system is good up to 700 hp..
if I were to go more than that I would need a bigger
pump and injectors.. the rest will work... the issue
with a 3/8 line that I dont like is the bends.. if
you get any kink at all it reduces the flow... the
ID is already 5/16" on a 3/8"
EDIT
Also... if you keep the stock tank I would add a sump
to it... injection doesnt like to have air sucked
in and if you run low in the tank it will suck air
in



Bigger is better when it comes to fuel line sizes, my next race car will have a 5/8 O.D. fuel ine with a 1/2 minumim return line, that is Carbureted, not EFI I'll put on what ever size the fuel stystem, probally Magnafuel, company recommends
