need help with equipment choice

[tekin]

Things I have:
327 with a RV cam all stock.
Holley Sniper EFI
Holley 565-100 dual sync distributor
MSD 6AL
Blaster 2 coil
MSD wires
Inline generic fuel pump (not sure if I want to do this or a in-tank unit).
is the factory fuel line good enough even though it is a 5/16 to feed the HOLLEY sniper or should I just change both lines and if so what is the correct line to get thanks.

Is this all overkill or what should I use as this is a just a cruiser and weekend car, should I do the Sniper and MSD or sniper and distributor, or all three. I just don't want to make it to complicated, but then again I have the stuff. Things I still need is a fuel pump setup. What do you all recommend besides an in-line pump I have, but not sure if that's good enough. Thank you in advance.

I've got the FiTech EFI, and per their tech support I was told that it would be better if I had 3/8" feed line and 3/8 return. This is what I did and never had a problem. I would think as far as aftermarket EFI kits they should all be along the same lines as far as the size of the lines.

ok great but do both lines have yo be high PSI or can the return line be lower and where did you buy the hoses from and do you know the lengths

Mine weren't prefabbed because I wanted them tucked and somewhat hidden. The material was SS tubing with rubber ends. I believe the return can be of a lower PSI, but I wouldn't think it would matter since the optimum pressure shouldn't be over about 70 psi. With the steel tubing pressure could be just about whatever without any problems.

ok so what you suggest I do as I can go anyway
I rather save money and put
One 3/8 fed line
One 5/16 stock return

But now you guys say both 3/8 lines
Also what is the full length front to back

no need to run a return all the way from the engine, just use a C5 FPR mounted near the tank.

5/16 return will work fine.
