You can check for air in the clear intake pipe to the filter. I could sometimes see a bubble in there before I started which dissapeared, but when I shone a bright light through the pipe from underneath I could see a stream of tiny bubbles against to top edge of the pipe. After I had removed and refitted the pipe the bubbles had gone, after about 100 miles they were back and the fault returned.

If you have the 2.0. engine it doesn't have an in tank pump, the fuel is drawn up by the HP pump.

You are correct Paul, i was covering all bases by saying pump/sender unit :)

Strange, I don't have one in mine, I took it all out to check the filter - no pump. Mine is a 2008 140 bhp though perhaps that's the difference?

AFAIK if you have a primer bulb there is no in tank pump, the casing for the sender unit is part of the design, can also house the pump if fitted ?

That's basically correct, The framework has enough space for a pump as well as the fuel level sender unit.

Is it possible that the sender unit is being mistaken for a pump?
