Whats a decent external pump to feed TBI? Most on Summit list something liek 12PSI(high carb pressure) and the fuel injection ones are something like 30 something and expensive.

11-14 is tbi pressure, 40+ is MPFI setup, carb, is 6 or so.

11-14 is stock TBI pressure. However this is going to be a 383 with 454 throttle body. I may need to push more pressure than that.
What about a "normal" EFI pump and regulator setup, feeding the TBI regulator? Might be a little more than you wanted to spend, but it also might be the best way to do the job...
Set the 1st regulator for like 20psi or so, and route it's output to the TBI regulator. I assume you're gonna run the vacuum-referenced regulator?

ford ranger pump. Would have to ask my friend what model it is. Works well.

hook up mechanical fuel pump on the block(if you can), plus your electric pump, join both fuel lines with a "T" fitting into your TBI...you'll get good pressure and volume. A friend did it for his 330HP 454...works good.
Try this one that goes in the fuel rail. Napa part# 5001. I think its about $140.
Airtex E8094, it is made specifically for TBI conversions. I have sold a bunch of these and have only warrantied one in the past ten years. I think it is about the same price as the NAPA one mentioned previous, but you might be able to find it for less if you shop around. Good pump, not too noisey, lifetime warranty, comes as a complete kit--fittings, mounting clamps etc.
