Fuel Pressure Regulator.

[richyb66]

I've got a 28/36 Weber and the standard Sierra mechanical fuel pump.

 

Do I need to use the Sierra fuel pressure regulator?

 

Do I need to pipe up the fuel return on the carb?

 

I the past I've not used a regulator and I've just Tee'd into the fuel line before the pump and piped the return into that - saves running a fuel return up to the back of the car.

You don't need the pressure regulator/vapour separator if using a twin choke webber and the sierra mechanical fuel-pump, nor a fuel return, although I would put in an 8mm supply and 6mm return pipe when building to save effort if you ever convert to injection.

Thanks for that Nigel, I'm probably a bit too late to easily add a return hose so I'll cross that bridge if I come to it. Most likely route forward after the Weber will be bike carbs or maybe a turbo.
