  Q: How to Release Fuel System Pressure While Servicing a Fuel Injector on Dodge Viper?

  A:

  Before servicing the fuel injector, release the fuel system pressure since the system still holds pressure even with the engine switched off. When yearning to replace just one injector, the whole Fuel Rail need not be taken out; it can instead be loosened and slid aside to reach the injector. Start by taking out the fuel rail from the cylinder heads and, once that's done, unbolt the fuel injector from the fuel rail.

  Q: How to Prepare for the Proper Removal and Installation of a Fuel Injector on Dodge Viper?

  A:

  Before you start work, clean out the fuel in the lines so it won't leak into the engine when you take out the fuel injectors. Follow the Fuel System Pressure Release Procedure with fuel hose #C-4799-1 connected to the fuel pressure test port. Take the windshield wipers and the cowl panel off and unplug the fuel disconnect line on the dash-panel. Hook the adapter, number #6539, to the fuel supply hose and pull the other end onto an approved gasoline container. Place up to 69 kPa (10 PSI) compressed air into end of fuel hose #C-4799-1 at the fuel pressure test port until the fuel inside is delivered through the fuel supply hose. When adapter number #6539 is removed, reattach the fuel supply line to the body fuel line at the dash-panel. To remove the fuel injectors, separate the electrical connection and label each injector with its cylinder number, should that be necessary. Disengage the injector holddown clamp, turn the injector to place the electrical connector at the intake manifold plenum, use a screwdriver to press it out and remove both the upper and lower O-rings. If you are installing the same injector that came with your bike, change the O-rings because each injector comes with new ones. Use a bit of clean engine oil on the injector O-rings and push the injectors into the intake manifold so the electrical connectors point to each other, except for the right rear injector that should face toward the back. Hook up the injector holddown clamp and screw, turning them by 11 Nm (95 in. lbs.) torque and then link the electrical connector to the injector. The DRB Scan Tool ASD Fuel System Test will allow you to pressurize the system and find any leaks.
