Car is 2001 DOHC
24 Duratec S-Type.
This is my parents car. I originally created the thread here:
2001 Taurus DOHC idle, power, vaccum problems
because of problems related to P0174.
I had some good responses from that thread. When I went out to work on it some more, I thought I'd look at the fuel filter. BTW, it is the three-port (nipple) filter.
It is the rustiest fuel filter I have ever seen!
Flakes of rust dropped off of it with a rub. It is my bet that it is the original part.
Here's the problem--well two problems, really.
I've been using the plastic collar-type disconnect tool. I'm able to "snap" it onto the 5/16" fuel-tank-side connector so that its base is flush with the end of the connector. I wiggle and pull, but can't get it off. (Also, I don't want to damage the connector!)
I bought these plastic disconnect tools probably before the car was built.
Here's what it looks like:
This piece is the 5/16".
From the top of the base to the top is a little under 1/2" (~7/16")
The total height is ~ 10/16" (5/8").
Am I doing this right? It seems that the lip (or ridge) on the filter nipples would hold the legs of the tool apart.
(In fact, it does when I try it on the new (unattached) filter.)
Are the legs long enough to disengage the fitting?
Having some trouble, I went and bought the scissors-type metal tool, but haven't had any luck with it. (Also, the business-end is no longer than the plastic piece.)
For the front fuel line, there is only about 1cm
(a little less, actually) of "gap" between the "quick-connect" fitting and the body of the fuel filter!!! Neither of these tools will fit in there!
Am I going crazy? I couldn't find the answer here or elsewhere on the inter-webs. Has nobody had this problem?
I'm not sure if the filter is actually the second filter the car's had, and if some yahoo put in an incorrect filter, but the new one looks like an exact match.
This (new fuel filter) could actually solve my P0174 problem. (I didn't bother with it before because I thought I would have had P0171, too, if it was the fuel filter!)
