2002 Cadillac DeVille Parts Questions & Experts Answers

• Q: How to replace a fuel injector on 2002 Cadillac DeVille?

  A: Start by removing the Fuel Rail followed by pushing the locking tab of the Fuel Rail until it moves toward the center to detach the Fuel Injector. Begin by taking off the upper o-ring followed by the lower o-ring before discarding the old injector o-ring seals. You must correctly position the new o-rings to prevent fuel leaks which could result in fire risks or personal injuries because when o-rings differ in color (blue and black) the blue o-ring should go into the upper position while the black o-ring should occupy the lower position. Always maintain accurate part numbers for new Fuel Injector purchases while the injector o-ring replacement should happen during every servicing period to stop vacuum leaks and driveability challenges. The new o-rings need engine oil lubrication before installation onto the Fuel Injector where they need to occupy lower and upper positions. Once the injector is attached to the Fuel Rail, all parts can be reinstalled.
