Airtex part # FS216
I've been looking for a new strainer for some time and every time you look under a Focus it does not show up, tried nearly every e-cat and paper catalog. Today I wanted one real bad and did some through research. Turns out the Jaguar S-Type uses the same pump and strainer/s. Yay for having Jaguar parts on my car
So if you have the update pump this is the strainer for you.
I'd recommend changing it if you haven't already and from that point change it every 2 years or 30,000 miles to prolong the lifespan of your fuel pump.
