Fuel Hoses Lines/piping And Fittings problems of the 2004 Subaru Impreza Wrx

Fuel lines on top of the engine leak during cold weather, below 10 degrees f. There is a strong fuel odor out side the vehicle and inside when the vents are on. The smell goes away after the car is completely warmed up, 10-20 minutes of driving.

Fuel line leak in engine compartment. Impreza sti '04. In cold weather, say less than 20 deg f, fuel lines leak at hard/soft line connections. Fuel can be seen dripping onto engine & strong smell of fuel inside cabin. Very similar to Subaru TSB 01-170-09, bulletin wvk-21.

During cold starts, typically under extremely cold temperatures, fuel leaks in the fuel delivery line could occur where the line connects with a rubber hose.

During cold weather startup, my Subaru will have a strong fuel smell coming from the engine bay and inside the car. Apparently, this effects many different Subarus during cold weather startup and a fuel line on top of the engine is the suspected culprit for leaking fuel.

There is a technical service bulletin concerning 2000 and later Subaru vehicles, including but not limited to the impreza, wrx, and outback. Under 14 degrees f or lower, the fuel lines connectors shrink to expose enough of the fuel line and allow fuel and vapors to release. The fuel can pool on the manifold, and the vapors can enter the cabin. This should be a major concern due to fuel and vapors.

Strong fuel smell on cold days when ambient temperature is below ~35-40 degrees f. Occurs without fail based on outside temperature and cold motor but goes away after engine has warmed. Dealer made minor adjustments (tightened lines) but states if problem returns, then fuel lines will need to be replaced.

The contact owns a 2004 Subaru wrx. In an attempt to drive the vehicle, the contact smelled a strong gasoline smell coming from the front end. He opened the hood and discovered a fuel leak on the fuel line near the intake manifold. The dealer was notified and stated that there was a service bulletin for this failure. The bulletin number was unknown. The current and failure mileages were 58,000.
