You should be able to run a mechanical pump with that 1406 carb. And, yes, you will need an electric one for FI if you go that route. Do a search in FI as there are some good threads on here from people who have tried or are using different ones.
I have a brand new (yes, it's brand new) one in my garage with a really nice K&N air filter setup on it. Ended up with it after some horsetrading on some Dodge truck parts. Looks pretty simple to me!
