My 95' 740i which has been laid up for about 5 weeks while I have been away suddenly begain leaking fuel when I started it for the first time. Left about a 6 inch puddle in the garage, and a steady path of drips out to the driveway. It seems to be coming from a small rubber hose on the undercarrage about 18" in front of the passengers side rear wheel. After running for a couple of minutes, the leak seemed to disapperar. The hose dosen't seems to be dry-rotted or fatigued. Other than the replacement of the small hose, is there another larger problem to worry about? (Fuel pressure regulator?) Any advice would be appreciated.
