I have the pump on the left. It is the port jutting out on the top left hand side of the pump that I need.Same problem, I can't view the photos without an account. You need to link the image file by pasting the image link into your Swedespeed forum post. If the image sharing service does not support that, try photobucket.
The photos below show the original Bosch 3 port pump as used on the D jet on the left and the later 2 port version of the pump which was used by Nissan on the 280 ZX.
The large diameter barbed port at the bottom of the photo is the outlet port which is part of the pump head casting. No separate fitting. If your pump does not look like the pumps in the photos, it is not the original pump.
The pump on the left is a little screwed up as it has a Djet pump head bolted on to a later K jet pump motor. As a result, the discharge port is 180 deg from where it would normally be on an original D jet pump.
