I haven't seen 1:1 on this pump yet, even after two different O-Ring swaps since they don't have a kit for the 1G AWD like Walbro does. The 2G and now EVO O-Ring must be bleeding off pressure as it's 5psi off at 31psi of boost and it gets lean FAST. 
I'm tempted to just ditch the pump or change the Fuel Pump outlet tube to a rubber hose to guarantee it's not bleeding by the O-Ring at WOT. The Walbro never did this.
Anyone chop off the outlet tube dome and run a short hose from the fuel pump outlet to the fuel hangers tube?
