How to Install a Fuel Pressure Regulator with a Pulsation Damper on 2008 Scion xB?

A thin layer of either gasoline or spindle oil should be applied to the O-ring on the fuel pressure pulsation damper before its installation into the 2AZ-FE engine. Use two bolts to mount the damper while reaching 9.0 Nm (90 kgf-cm, 80 in-lbf) torque with verification that the O-ring remains intact without any damages throughout the installation process. Follow the fuel main tube installation and place the air cleaner cap sub-assembly when connected to its hose. The inspection for any fuel leaks needs to be conducted before installing the No. 1 engine cover sub-assembly.
