EFI fuel tank/pump questions..

[morethanstock66]

I know this has probably been asked before, I was just not able to find it. I am very green when it comes to fuel delivery.

I am looking to put in a new fuel tank. I currently has the OE tank with a carb. I am looking, in the future, to make it EFI. But for the time being, it will remain carbureted. I am just wanting to move the tank out of the cab, as a lot of people have. My question is can I put in an EFI tank and pump with a fuel pressure regulator and have supply correctly, then when I swap to injectors use the same tank and pump? Or would I have to get a new tank/pump for each situation? Any help would be appreciated. Thanks!
