Hey All

I'm more or a lurker on this site, and it has helped me out so much in the past, but now i need to ask a question of my own!

I have a problem with the XF where it stutters between 1500 and 2000 RPM. I am pretty sure its the fuel pump/filter. My questions are;

Is there a pump and filter, or is it just one part? (dumb question, just wanted to check)

Which is a good replacement, is there a decent aftermarket or is OE the best way to go?

Many thanks!

John
