I have a 07 Impreza non turbo donor and my fuel pump is shown





This is different than the one in the manual which I think is from WRX turbo charged. Mine has two send and return tubes on the top of the mounting plate instead of three as shown in the manual. I think mine are fuel pump out and jet pump in?

My questions are #1. do I need to come up with my own vent system?

And #2. Do I just leave that little plastic venturi pump thingy in place instead of removing it as in the manual?

Thanks
