Relieving Fuel System Pressure


Specific to:

Toyota Corolla 2006-2008

Failure to relieve fuel pressure before repairs or disassembly can cause serious personal injury and/or property damage. Fuel pressure is maintained within the fuel lines, even if the engine is OFF or has not been run in a period of time. This pressure must be safely relieved before any fuel-bearing line or component is loosened or removed. On vehicles equipped with inflatable restraints or air bag systems, wait at least 90 seconds after disconnecting the battery cable before performing any other work. The back-up power will keep the restraint system energized for a period of time after the battery is disconnected.

  1. Before servicing the vehicle, refer to the Precautions section.
  3. Perform the following:

    Remove the fuse for the fuel pump
    Start the engine until the engine stalls
    Disconnect the negative battery cable
    Place a catch-pan under the joint to be disconnected. A large quantity of fuel may be released when the joint is opened
    Wear eye or full face protection
    Place a shop towel over the area and slowly release the joint using a wrench of the correct size.
    Allow the any fuel left in the line to bleed off slowly before fully disconnecting the joint.
    Plug the opened lines

  5. After connecting fuel lines, install the fuse for the fuel pump and start the engine.
