I'm in the process of planning to integrate my external fuel pump and regulator into my fuel system and need the inlet and outlet thread sizes of the Fuel filter used on the V6 Fiero (should be the same as some earlier fwd cars) and the fuel rail return line fitting on early engines with the same style fuel rail, in order to purchase the adaptor fittings needed.

Thanks for any help that can be provided.
