My name is earl mckeever, I have a 2004 Nissan Titan I've had my vehicle in the shop 5 times from the fuel rails leaking within the last 4 mth. This did not just start the fuel rails have been leaking over the years I just did not know what the smell was coming from. Once the pressure build up it stops leaking that why I could never see the fuel leaking, until one morning I cranked up with the hood up. The thing is these fuel rails leaks the fuel on the engine and I know Nissan know's this.
