Converting TPI to carb....questions within

Hey guys. Here's my dilemma. I have a '90 GTA that has a brand new in-tank fuel pump that really is sweet, but I'm dropping my carb'd 350 from the '82 into and is it possible to use this pump with a carb with a regulator or something in order to drop the pressure down to a resonable level?

Well since I can't help and it looks like no one else wants to I can try and point u in the right direction. Try talking to Jester or one of the carb guys from the Carb Forum. They should know.

Yes, Mallory sells a 3-50 psi regulator for around $70 in Jegs that will work. I've been running it on my previously TPI'd car (stock intank TPI pump) for about a year or more I guess. It is a return style regulator, so there are no problems w/ the pump overheating or anything.

I have an 85 z-28. Can the car function without the computer hooked up and running the engine?
