The first question is why? What are your goals?

An electric pump is different than mechanical in a lot of ways. It's not a huge project, but there are some issues that you need to pay close attention to:

Wiring:
- Obviously, you need the power and ground wires.
- With EFI, the computer controls the pump. When you turn the key, it runs for a few seconds to prime the lines. If it doesn't see any RPM's, the pumps shuts off.
- Same thing when the engine quits. No rpm's = no fuel pump. Helps prevent the kind of damage mentioned above. Also prevents the tank from emptying in case of a crash.

Hard parts:
- need a place to mount it. Needs to be near the tank, and as low as possible.
- Most pumps require a return line.
- You need two filters, 100 micron before the filter, and 10 micron after.

Other considerations:
- Electric pumps can be noisy.
- They're not as reliable as mechanical pumps. I'm on my third A1000.
