I wouldn't buy APS anything!!!
What you want is the CJM stage 2 return fuel system. It's the best one out there by far.

His name is Charles, and knows the 350Z fuel system better than anyone. he can answer any quaestion you might have.
If your looking for over 600WHP Charles just came out with an amazing twin Walbro 255 in tank pump setup that is CNC machined. Beautiful!
Don't waste your money with AAM or APS.
BTW charles uses firesleeve on all his fuel lines that pass in the area of the exhaust and engine compartment. His fittings are the best available.
