• Q: How to service the fuel pressure regulator on 2007 Scion tC?

  A: The first step begins with discharging fuel system pressure and removing the negative cable terminal before starting service on the fuel pressure pulsation damper. Start by removing the engine cover sub-assembly together with the air cleaner cap sub-assembly and disconnecting the fuel main tube. Begin the fuel pressure pulsation damper service by removing its 2 bolts. Symmetrically apply a gentle coat of gasoline or spindle oil to the O-ring of the fuel pressure pulsation damper before securing it with 2 bolts that must reach 9.0 N.m (90 kgf.cm, 80 in.lbf) torque and should never exhibit O-ring damage or obstruction. The next installation process involves the combination of fuel main tube installation followed by air cleaner cap sub-assembly installation along with engine cover sub-assembly installation before reattaching the cable to the negative terminal and inspecting fuel leaks. After cable removal from the negative battery terminal users should conduct initialization testing for systems that need this protocol.
