    I just need a little clarification, I plan on swapping my 86 and converting to fuel injection. Do I need a whole new gas tank or can I just put a new pump in the old one? I've looked a little for an si for parts but no luck so far in my area.

    Your supply and return lines are smaller than the fuel injected cars...that's the issue with the tank
    -also the pump is external on an Si, not in the tank

    you can run new/larger lines and install an inline pump or swap it over from an Si if you can find one

    you'll also need to either wire in a relay and switch to turn it on, or again if you find an Si you can use its ignition switch and harness as it has the 3rd wire to turn the pump on

    best bet is to keep searching and hold out for an Si parts car...makes the swap 1000x easier
