How does my contraption look??
Lemmie see if I can splain it better with pictures. Forgive my caveman drawing, but it's all I got. first, here is the diagram from Barry Grant.
Look at how the regulator is positioned. It will act like a restrictor to the carburetor trapping fuel AT the carb. The regulator in this diagram is actually plumbed in the return line.
Here is my caveman drawing. Yeah, I know it's rough, but bear with me, ok?
Notice the position of the regulator. It is in the supply line. Also, see how the carb is RIGHT between the supply and return lines. In this fashion, the carb itself becomes the exchange point for cool fresh fuel. And trust me, the ENTIRE fuel volume of the bowls is exchanged every few seconds, not just the top. And yes, a restriction is required in the return line. If there is none, the fuel pump will not be able to generate enough fuel pressure. I have tried it. I like the Holley jet idea in the return line, because that way, you can actyally taylor the return back pressure instead of it being fixed. Doin the fuel system like this makes the fuel go ACROSS the float bowls and covers the bowls completely. Doing it conventionally, you essentially are asking two things of the same line. Pressure and return. This isolates the return system completely. It allows warm fuel to be purged from the float bowls, releives stress from the fuel pump and recirculates the fuel at a much better rate. It's worked well for me for a long time and I know many more people that do the same. Lastly, you can do all this for about a third the cost of all that fancy stuff in the BG diagram. Does it work better than the BG system? Hell if I know. But it works for ME. Yeah I know.....there ain't no fuel pump in my caveman drawin. But let's pretend, ok?
