Hmm, that Volvo turbo looks like fun.

How much power are you planning on making? That will determine what fuel pump you need. I recommend a surge tank if you plan on doing any hard cornering under boost with less than like a third of a tank of gas. As far as fuel pressure regulators, Mallory 4309 or Aeromotive 13301 have good pressure ranges. The Aeromotive one is more expensive, but comes with a high-pressure spring so it can also be used with EFI.

i was looking to run 8-10 psi. i was told 10 psi with that turbo would make 300 hp which i dont fully believe.
iam not looking to make insane power, since this is my daily driver during the summer. the reason i went with this turbo is i got it dirt cheap, cheaper then i could get a TII turbo and i would not have to deal with making a adapter plate for its manifold.
i figured i all ready have to make some thing to mount a turbo mani on my motor 12a,if i went with a TII manifold. i could just start from scratch and build a custom one to have the turbo in a better spot.
ill save my self a lot of work this way since i wont have to buy a TII mani, make a adapter plate. then machine my stock intake,then weld it shut again so the turbo will clear it like others have done. i plan to run the stock carb turbo prepped at frist then when i have money get a new intake carb.

i looked at mallory 4309, it says nothing about being a rising rate fuel regulator. i thought i need a 1 to 1. like for every pound of boost it needs to rise one pound.

edit i realized i misread there web site.
any ways now that i got the regulator picked out, now on to the fuel pump.

i have yet to find a drop in replacement for my gas tank and would not want have to run a fuel cell. i figure i would have to drop my fuel tank any ways to run the return lines. but my real question is this could i use my stock fuel pump and then use a Aeromotive In-line EFI Electric Fuel Pump, P/N 11109. it says it can be used on efi or carbed cars after the in tank pump. the way i read the specs on there web site it seems i can put this after my intake pump to get more fuel or am i miss reading some thing.

You don't have an in-tank pump. The stock 12A pump is external and sucks. What I'd do: get any external pump that has a decent free-flow rate (Carter, Holley Red/Blue, etc.) and use it to feed a surge tank (Tweakit sells them or you can make your own), and use a Walbro 255 after the surge tank. That ought to be good for over 300 HP. I'm not sure about line sizing, though.

my bad thought it had one stock so iam going to be running two pumps no matter what.
