Heh, I bought the exact same pump on my Cobra clone. I had to grind off part of the accessory bracket in order to get the return line on the pump. Sadly I don't have any photos of the mods I did. I basically ran the return line off to the side towards the left fender, rather than go out the back like the OEM pump. I'd also recommend using a screw clamp on the return line, or it's going to leak. The bend you'll get in the return line will make it not want to stay on the pump very well.
