Diesel dripping from behind 100s glovebox

G'day All, this is my first post.

I have just purchased a 2001 LC 100 series factory turbo diesel auto.

There is diesel dripping on my wifes foot from under the glovebox, not happy Jan!
A forum search led me to posting 38822 on this subject, posted by 'Pedirka (Tony)', but it did not provide the solution. The posting alluded to a possible leaking diesel controller or pump, and the diesel leaks back along a sensor line through the firewall. The wiring loom behind the glovebox is wrapped in foam rubber and this is soaked in diesel.
Does anyone have experience with this problem - do I need to replace the diesel pump or just the sensor fitting. Any other suggestions???
It would be nice to know of others experience before I ask Mr Toyota.
Cheers, Dalb
