2008 Ford Crown Victoria Fuel Rail Parts Questions & Experts Answers

• Q: How should one service the fuel rail while ensuring safety and preventing fuel leaks on 2008 Ford Crown Victoria?

  A: Safety measures for servicing fuel rail include keeping all flammable mixtures away from fuel components because they harbor open flames or smoking materials. You should decrease fuel system pressure in advance of every fuel tube or component disconnection to stop uncontrolled fuel dispersion. Place the vehicle on a hoist and set it to NEUTRAL gear as the first step before turning off fire suppression if it is present. Revoke fuel system pressure from the system while also removing the battery ground cable. Begin by removing the fuel tube spring lock coupling from the fuel rail followed by the throttle body after which the EGR system module tube needs to be removed. The brake booster vacuum hose along with evaporative emission canister purge valve hose and PCV tube and intake manifold vacuum hose should be removed from the throttle body spacer for later placement apart. The crash bracket wire harness retainer can be disassembled only if required. After detaching this component you can remove the crash bracket by unboltting its two fasteners while torquing them to 25 Nm (18 lb-ft) when reinstalling. Uninstall the wire harness retainer from the left front fuel rail stud bolt while separating the eight fuel injector electrical connectors with their ground connector from the right rear fuel rail stud bolt. The technician must disconnect both vacuum lines from the fuel rail pressure and temperature sensor in addition to removing the electrical contacts from these sensors as well as the vacuum lines from the EGR system module and its accompanying electrical connections. Tighten the two shield bolts at 12 Nm (9 lb-ft) during reinstallation of the shield after removal. You need to take out the four fuel rail stud bolts which require a tightening torque of 89 lb-in before reinstallation then remove the fuel rail together with its fuel injectors. New O-ring seals made from special fuel-resistant material should be used instead of old ones for leak prevention. The vehicle's fire suppression system requires activation in cases where new fuel injectors should receive clean engine oil during lubrication of their O-ring seals before reinstallation.
