I've changed this filter before 2 years ago. If memory serves, it was a bit firm back then but I don't remember grumbling too much about getting it out. I'm crap with mechanics but even I was able to get it done.
Today, 25 months on I came to do it again & the damn thing was stuck. The housing looks like this:
It's the one with the screw in the centre of the cap. Now it was starting to round off so i didn't bother unscrewing it. I don't know if this will have made any difference to this issue or not.
I popped off the cap, it was more filled than i remember from last time but i can't be 100% certain on that.
I tried to remove the fuel filter and it was a no go. I used a flat head to pry it and still no go. I used a set of adjustables to try and grip light enough and twist and pull and still no go. Back to the hand but this time using a cloth to help grip and still no go. Two screwdrivers under the plastic lips and still no go.
In the end i broke the plastic ring off as shown in this image:
So i gave up and put it back together.
How on earth do i get the damn thing out and why is it likely to be sticking so bad? I was pulling on the filter so hard it just lifted the housing straight up off the brackets and away we went.
