Really strong petrol smell when driving home tonight. Popped up the bonnet and got hit by a spray of petrol. The middle metal fuel hose secured onto the bulkhead has a pin prick hole in it. I did get worried when the petrol was dropping onto the hot exhaust underneath! Dark and raining at the moment, but seems the hose runs along the bulkhead and under the airbox. Is there an easy way to repair one of these hoses or is it a replacement?
