I feel a bit of a berk having to ask this - but for years I've been putting up with being unable to drain water/fuel from the fuel filter drain plug.
Plug opens, nowt comes out. So I have to unscrew and take the lid off, so air can get in and the fuel comes gushing out.
Am I missing something? (it's the post-1990 filter design that sits above the clutch, on a Xsara).
