Silly question really-How does the electrical wires unplug from the bottom of the fuel filter? I can't see up in there, and the service manual goes into no detail. I want to be sure I don't FUBAR it up when I change the filter. Thanks Ken |

I always unbolt the filter from the firewall. Makes everything easier, especially unplugging the water sensor on the filter. |

It's virtually the same as all the other connectors. You squeeze the fin sticking out of the connector and remove the whole assembly from the part it's attached to. Not to confuse you, but ONCE YOU TAKE THAT CONNECTION OFF, the sensor on the bottom of the filter threads in and out of your filter for attachment to the new filter. Hope that helps. |

There are generally 2 types 1) a tab, often red, needs to be pulled out to unlock the plug or 2) a flange or fin needs to be pulled pushed to one side to clear a tab and unlock the plug. I don't recall which one the fuel filter has. However, if you simple undo the 2 nuts that hold the filter head to the mounting bracket there is ample flex in the hoses and wire to that plug to lift the assembly up and undo the plug in the clear. Frankly I prefer to remove the whole assembly from the vehicle to change the filter although you don't have to and doing so does involve removal of the fuel line and 2 electric plugs to the head. If you go this route be sure to push the fuel lines off as trying to pull them off just makes them grab on harder. FYI if you have a 1st gen filter head consider replacing it now with a 2n gen head costing ca. $125 (head and wiring pigtail) but it comes with a brand new filter already installed. |

Now that you now know how the plug works, you can remove the filter without taking the housing off the firewall and, if you put a rugged (like a ziplock) plastic bag around the filter after unplugging the WIF sensor and loosening, but before removing, you can do it without spilling nary a drop. Also, if you have a lift pump, you do not have to bother with prefilling. Just run a clear hose from the bleed nipple to a catch bottle, loosen the fitting and turn on the key until you have strong flow with no bubbles. Should then start and run instantly as normal. DOC |
