Fuel regulator for TBI to Carb Swap?
Okay so, I'm in a hurry tonight, or I'd run a search, and I have a quick question before i head out. I want to install a pressure regulator so as to keep my fuel pumps but swap from TBI to carb. How do I run the return line? Thanks in advance. Pictures would be a HUGE help if any of you have them.

Re: Fuel regulator for TBI to Carb Swap?
Return line is already there if TBI - just need to connect return line to correct port on the return style regulator (ie the bottom on a Mallory 4309). If you need extra length, you'll need fittings and extra line or fuel hose to connect - it all depends on where you mount the regulator.

Yeah just use the Mallory 4309. It's pretty much the standard for this sort of thing.
