stock pumps have the fittings on the top. The output lline runs up behind the PS Pump to the carb. I had a heck of a time bending and fitting a new line for mine.

After I did some more changes, I installed a Carter with the fittings on the bottom and plumbed it all with AN fittings & hoses to the regulator and press gauge.
