I was thinking more the rest of the system, other than the carb.

I currently have a unknown modded prepped NIKKI/ Mr, Gasket pump/ Fuel Cell

Waiting for my Sterling to come in, Carter 7LB pump(not on yet, this weekend hopefully) Holley 1-4PSI regulator. Going to try to modify my stock intake to flow a little better, but will be buying a spare, because I'll most likely screw it up.

On my last 13B bridge-port setup, I was running a RB 650 DP carb, Aeromotive A1000 pump, System 1 billet filter, Mallory 4309 rising rate regulator, -10 supply braided line and -8 return braided line. This system also pumped the fuel for the 100-150 shot of N2O wet/plate system.

I have a Carter pump that needs to be installed, dont remember which model number. Its the 6psi, 72GPG one. Going to dead head it into my Weber, as webercarbs.com recommends.

Aeromotive pressure regulator, 6AN lines and fittings, and Chevy TBI style fuel pump. Went with this fuel pump because it's an in-tank pump, easily accessable, cheap, and fuel pressure on TBI pumps are low enough to be regulated. (I think I remember it being around 12 psi) You must use a bypass style regulator since the pump holds pressure after shut off like any other EFI pump.

Carter pump w/Holley fpr. Then I added a fuel pressure gauge from Respeed (highly accurate, and dirt cheap).

Here's a writeup I did on my installation, with lots of input from others, posted over on the "evil forum".
