Hi guys, iv got a facelift 56 plate vectra c SRi 150 CDTi. What mudflaps do i need? And what are the vauxhall part numbers?

I also have a strange fuel probem. If the range get down to around 30 miles and you acellerate around a corner, the car with spanner light will come on and the engine will cut out. If you turn the igntion on and off again it runs as normal.
It doesnt do it any other time unless its low on fuel.

Cheers,
ben
