Need to get bigger fuel pump that will handle supercharging. What size should I get?

I have a 93 GT with a slightly modified engine. Eventually I will be supercharging it (vortech S-trim 9lb.boost) I need to get a bigger fuel pump now that will handle supercharging later. What size do I need? Will a 50gph(198lph) be enough? Should I go with an inline or just an in-tank pump? Right now I have 24lb. injectors. I would really appreciate anyone's input.

run a 255 lph just to cover anything possible side effects.

Ok a 255, but in-tank, or in-line? Also, what fuel pressure?

in tank.. they make o.e replacements.
fuel pressure around 38 N/A and around 42 with forced induction.... you may have to tune it for your specific setup but thats a good reference.
