    I'm to the point of removing the fuel rail and injectors and I haven't seen anything in the on-line manuals about depressurizing the fuel system. Does it need to be depressurized and how? Or, not?

    Thanks,
    Kurt

    Relieving Fuel System Pressure

    Toyota Pick-ups, Land Cruiser, and 4 Runner 1997-00

    To relieve the fuel pressure, wrap a clean shop cloth around the union bolt (banjo bolt) at the fuel delivery rail. Slowly loosen the bolt holding the fuel line and allow pressurized fuel to escape into the cloth. Do NOT allow fuel to spray from the fitting; always wrap it in a clean cloth.
    Pressure may also be relieved at the fuel filter, if desired. Tighten the union bolt.

    Also, you can take out the EFI fuse and crank the engine for a few seconds. :)

    That only de presurizes the gas tank. The fuel injection can hold psi for a LONG time. :)
