My car smells of fuel in the cabin and boot on start up and for the first few miles, but only when its been standing for a few days. I've searched the threads on this topic. I've removed the osr (driver's side) wheel arch liner and checked all the pipes. I changed the fuel filter about 6000 miles ago and checked the the pipes around the filter and pump - it all looks fine. I haven't yet removed the nsr liner, but if the lines here are OK, could it be that the charcoal filter needs replacing, and would a symptom be the fuel smell? The car has been family owned from new, and has done nearly 149,000 miles (I don't think the filter has ever been changed).
