Best things I can tell you how I've always did this and many others also.
Whichever side of the motor you put the pump run the hose thats pulls out of the valve cover to the opposite side and to the front of the valve cover. Several places sell a AN fitting that has a nut with holes on the back you can use just by adding a hole in the valve cover.
2nd thing .. I put the regulator right to my pump, aim to pull around 8-9 at idle.
My current setup has no regulator on it, it can be ran this way just have to watch the gauge more.
