First of all you've apparently been reading about Perry pumps? They are a pump with a pressure limiting device.

The Cline is a demand regulator or a balanced Zero regulator. There's no pump to it. You have to tap the crankcase and use the supplied duck bill check valve to pressureize the tank and force fuel to the engine. There's no pressure on the outlet of the regulator. There has to be a slight suction for there to be any flow through it.

I've seen the Cline's rigidly mounted between the remote needle and the carb. The Cline should be as close to the spraybar as possible, whatever you do. But it's actually better to have the needle valve after the Clane than before it but I think you can get by?

If you use the big fuel line, you will ned to run big tubing in your tank as well as the big pick-up. You are going to have to use clamps on the fuel line at the Cline. Its also best to use the clamps elswhere. Not everyone uses the big fuel line though.

Enjoy,
