You will need a low pressure fuel pump, something that puts out in the 4-6 psi range but flows alot. From what I have been reading the Carter fuel pump seems to be about the best on the market. Whether you run a pressure regulator or just dead head the pump into the Weber is up to you. Some people need regulators and others like webercarbs.com just recommend dead heading it.

I just dead head my pump, I have a cheap pump in there now but have a Carter that I need to put in.

You'll also need to figure out what to do for ignition, as the FC computer won't be able to know what to do without a TPS, AFM and so on. You could do a megasquirt and add a TPS to the carb and do it that way, or you could do it the inferior way and put an 12A distributor on it.

You'll also need to plumb the system to give a brake vacuum source, and you may need a longer throttle cable.

You'll also need to tune it, so you'll need to find someone who has the tools and expertise to do so, or learn to do it yourself with the help of a wideband.

There's a lot of little details, it's not like you can just bolt it on and drive.

The 12A dizzy isnt really that inferior. I mean, you can still use the FC leading coil and still have a wasted spark ignition. Alot of the FB guys do this.

Distributors are inferior to a computer controlled individual coil ignition system, period. Sure you can make a dizzy work ok, but you're still lacking the degree of control that the stock type system will be giving you with a Megasquirt or something like that controlling it.

There's a reason dizzy's aren't used anymore.
