[Gav]

I have used a reg bought from Ebay. It was flogged as being the same as a sard.
Mike and Phil N have both used sard regulators so I thought it would be a good place to start.
I have a 3/8" line up from the tank, a stock commodore filter on the passenger footwell that then feeds the fuel rail. I have bronzed a 5/16" barb into the drivers side rear of the fuel rail and from there go to the regulator that then feeds back to the tank.
There is a pic in my gallery of the engine bay with the fuel lines fitted, its a bit dark but you will get the idea.
