fuel tank sump...some questions

I'm considering doing a fuel tank sump on my '92 RS. I just have a few questions about the process:

1. If i sumped my tank on my TBI setup, would I have to run a special fuel pump for the nesseccary fuel pressure the TBI needs?

2. What size bungs would you reccommend, 3/8" or 1/2"?

3. Would I have to connect to the existing fuel lines or could I run all new lines?

no reason to waste your time if you're running a TBI setup. Pull the tank and put in a walbro 255 pump and it'll be more than enough for any tbi setup.
