Erik,
I was sure someone had responded to this already. Apparently not.
Yes. There are different pumps for different power requirements. The standard Tanks Inc pump isn't going to cut it. You're going to want the GTA4. It's equivalent to a 255 lph (like a Walbro).
But yes, you're going to have to use a fuel pressure regulator of some sort, because generally speaking, fuel injectors are designed to work on a set fuel pressure. I generally set them to 58 psi, but your Atomic EFI might be different. I am not experienced with those, as I primarily do LS stuff. The TBI stuff usually takes around 10-13 psi.
I have seen lots of people use the stock hardlines. But I recommend using new ones at the very least. (As a matter of fact, I always make new hardlines on every EFI conversion I do.) The truth is, the factory hardlines were designed to work with a carburetor. Old rusty will NOT do. The new fuel injectors have very small orifices, and are clogged/damaged easily. Moreoever, they just don't plug in like they were meant to. Which 1) looks bad and 2) usually calls for some poorly made connector line to fill the bridge between where it wanted to end and where it needs to end. Fuel line is so darn cheap, and there's so many versions of connectors to use at either end, I don't see the point in keeping a hard line unless it's brand new. Lastly, the hardlines don't have provisions for fuel pressure regulators or fuel filters. One more for replacing it with a line you make or have made.
