I have a SARD FPR but the instructions are in Japanese. I have never fitted one of these before and would like to know which lines to connect where.

I have a gauge to connect as well.

There is 1 1/8npt at the botom, and 2 on the top. Also there is a vac nipple on the top.

I know where to connect the vac nipple to.

Do I connect the supply (from secondary rail) to the bottom, and the return to tank+gauge in the top? Or is it the other way round?

Thanks
