    Question Bleeding fuel lines to change filter

    I was looking up how to change out the fuel filter in my '06 WRX and it seems pretty straight forward, but I was wondering how to bleed the fuel lines properly. I attempted to take out the fuel pump to get to my filter but the main fuel line kept spraying fuel out pretty quickly and wouldn't stop. I had about 1/8th of a tank left, should I drain it completely first or can I still do this with some gas left in the tank?

    Relieving Fuel Pressure

    1. Disconnect fuel pump relay connector
    2. Start and run engine till it stalls
    3. After stalling crank for 5 more seconds
    4. turn ignition off

    Fuel Filter Removal

    1. Relieve Fuel Pressure
    2. Remove pump assembly
    3. Remove fuel pump
    4. Separate pump from filter

    Install in reverse order

    Make sure you clean off the top of the tank so no debris falls into the tank and no you do not need to drain the fuel just relieve the pressure

    Sweet, that sounds pretty easy as well. After all the fuel sprayed out everywhere, the top is already clean haha! Appreciate the info and the help!
