Thanks. It's going in on Thursday - I'll definitely ask them to check on that. I assume the filter could be the other cheaper cause of low pressure if it's caked a bit, though I think that's been replaced relatively recently.
Ah when it was changed, were there any metalloic bits in the old filter.
What brand is the new fuel filter? Some fords (mondeo from experience) suffer with fuel filter causing starvation so only certain brands, from certain factories seem to be trouble free or ford original.
Might be worthwhile to check the pump is the actual issue, not a wiring issue or debris from the fuel affecting the sensor.
