Fuel line broke and leaked gas onto the hot exhaust system. The fuel leak was from a fuel hose on the firewall. The fuel lines are leaking in several other areas underneath the car.
Fuel line leak in the engine compartment. Fuel line material was deformed and resulted in a small hole where fuel was spraying directly on the turbo, cat and related exhaust components. Vehicle continued to run and did not shut down or show signs of a fuel leak.
2004 vw Passat 4-motion wagon with 1. 8t engine. Top of fuel tank is leaking at the point where a breather hose connects (which is under the left rear seat). Replaced breather hose. Gas continues to leak out. The connection point itself is cracked and a new fuel tank is required. This must be a design flaw or defect. The car has little over 71,000 miles. Car is out of warranty. I am original owner. No unusual or hard impacts to the car (it has only scrapes from anonymous, unscrupulous bad drivers in parking lots). Vw of America refuses to cover the cost for replacement (conversation with customer care department representative "nina" on July 6, 2010). This is a very dangerous defect or flaw. Raw gas should not spill out of car -- particularly in this location, under a passenger's seat. Volkswagen should post a recall and replace this part with a safer tank.
