Jez850 Posted July 7, 2016 Share Posted July 7, 2016 Hi All, When my GF is driving her Mk4 with the windows open a smell of petrol enters the car. Upon investigation the smell seems to come from the filler area but not the filler itself. I cannot see any evidence of a leak anywhere and the exhaust does not seem to be blowing. Does anyone know of any weaknesses in this area - maybe the filler pipe? Quote Link to comment Share on other sites More sharing options...
Ian Lanc Posted July 7, 2016 Share Posted July 7, 2016 Any smell of fuel warrants a serious look around, just follow your nose! Look under the car ? Fuel pipes ? Fuel filter ? Signs of past leakage ? Or maybe the car was over filled with fuel and being thrown out as you drive ? 2 Quote Link to comment Share on other sites More sharing options...
dave1987 Posted July 7, 2016 Share Posted July 7, 2016 My old mk4 did this too but only after brimming the tank with fuel. Did she just fill it up? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Ffoxy Posted July 7, 2016 Share Posted July 7, 2016 Have a good look for rust at the fuel tank and filler pipe. Sent from my iPad using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk No not over filled still same quarter tank to three quarter tank. I have smelt petrol though so will check rust at fuel tank and filter pipe.

Jez850 Posted July 19, 2016 Author Share Posted July 19, 2016 Hi Guys, Sorry for late reply and thanks to all who have helped with advice. The smell is intermittent and is not as a result of overfilling. She periodically gets the engine management code for fuel tank air pressure/leak, which normally resets ok after reseating the filler cap. Maybe there is a leak somewhere after all. There is some light surface rust on the tank near the filler but no smell there. Will the filler cap neck be visible if I remove the wheel arch cover?
