Wiring to the sensor more likely than sensor itself but the well documented problem of leaking fuel pipes under filter could also be your real cause.

Its air leaking in NOT fuel leaking out your looking for :)

The pipes you mention are they the ones going to and supplying the filter or from the filter to the rail ?
i will check the wiring this evening if i can get to it as its on my expert van and its a pig to get to the back of the engine
?
many thanks for your response any help is always greatly apreciated :thumb:
