Fuel line leak
Complainants report fuel leakage most frequently in winter during initial cold engine startup.owners will either notice a fuel odor inside the occupant compartment or fuel odor/leakage at the fuel lines on the right side atop the engine. Once the engine has warmed, the odor/leakage may cease.subaru revised the fuel pipe/hose design for model year (my) 2003-04 wrx vehicles produced after august 2003.subaru also introduced a my 2004 impreza sti vehicle with a different engine and fuel pipe/hose layout.out of the total of 994 complaints, 944 concern my 2002-03 wrx vehicles built through august 2003.subaru also reports one fire on a my 2002 wrx vehicle that occurred in february 2006.in march 2009, odi inspected and video taped a my 2002 wrx vehicle with a fuel leak during cold engine start up.the video was provided to subaru and is in the investigation file.

What 2004 Subaru Impreza owners say
Most recent owner complaints, unedited.
There is a recall for fuel lines for MY2002-2003 Imprezas and the issue was resolved or a fix was implemented on late MY2004 vehicles. Unfortunately this means early MY2004 vehicles are still impacted by the issue with no recall in place. During cold weather or during cold engine startup fuel lines are prone to leaking onto cylinder head. Raw fuel can be observed dripping, and can be smelled in the engine bay and inside of the vehicle. This poses a fire risk during vehicle operation and the MY2002-2003 recall should be extended to MY2004 vehicles built prior to August 2003.
Rubber fuel lines under the intake manifold leak fuel when the temperature falls below 40 degrees F. The smell permeates the cabin and fuel can be seen wetting nearby surfaces under the intake. An inspection can be performed. This represents a fire safety hazard that could occur while the vehicle is in motion, jeopardizing all surrounding traffic. The problem is widely noted on Subaru internet forums, but only a recall for 2002-2003 models has been reported. My car is a very early 2004, so it shares traits of the 2003 engines. There are no warning lamps or notifications, only the smell of raw gas when the car starts and is in motion in winter temperatures. This has happened repeatedly since the issue first occurred, so I avoid driving this vehicle if at all possible.
There is a strong fuel/gasoline smell coming thru the air vents from the engine when the temperature goes under 30-25 degrees farenheit. I've checked under the hood and there is two fuel hoses that start leaking when it gets cold outside. This has been happening every winter since I got my car back in 2016. I had the clamps on the hoses retightened by a subaru dealership but that didn't solve the problem. I'm writing this complaint because there is an open recall for this issue on the 2002 and 2003 wrx, but not on the later models. There's many people on the internet with the same issue and it seems to be happening to other years of wrx and even other models of subaru. It's really stressful and annoying having the strong smell of fuel coming in to your car. Also it's a fire hazard having gasoline pooling up on the engine block. This issue has been known to subaru of america but they only took care of the 2002 and 2003 wrx models. I'm hoping this can somehow help other subaru owners get this problem fixed as it can be something that could end up getting worst.
I arrived at a gas station where I filled up my subaru impreza rs 2.5l with 87 unleaded mid grade fuel and from that point on still till today my vehicle has has the check engine light on, when the air conditioner is turned on and I'm going 55 MPH or higher gasoline can be smelled within the vehicle. When refueling the gas pump continously stops as if the fuel chamber is full. After refueling the vehicle fails to turn over or staggers weakly to start.
Tl* the contact owns a 2004 subaru impreza. The contact stated that the check engine indicator illuminated. Also, when the contact filled up the fuel tank, there was a strong odor inside the vehicle. The contact also located fuel inside the vehicle on the rear driver's side. The vehicle was taken to paul miller subaru (3469 us-46, parsipanny, nj) where it was diagnosed that fuel was leaking from all the fuel lines under the vehicle. The manufacturer was not contacted. The vehicle was not repaired. The failure mileage was 110,000.
Driver side fuel line that is connected to the fuel rail underneath the turbo inlet hose leaks gas. The smell is very noticeable and I'm pretty sure it's dangerous since it could cause an engine fire.
During cold weather a strong smell of fuel can be detected coming from the engine bay while both moving and stationary. This problem only occurs during colder weather.
During the past 8+ winters, there is a strong fuel smell. I've called subaru of america and they said that only the two previous models were recalled for this problem. According to my resarch, it sounds like this problem persists with many subaru models. I've been able to close the air vents to keep the smell out in previous years. Today, white smoke started to come out of my hood while driving and stationary. The temperature is in the single negative digits.I believe there is now enough fuel leakage onto the manifold that it is starting the smoke.
It recently been cold in colorado and now I have this raw fuel smell in cabin during cold weather. Fuel line leaking coming from the rubber hose connector located under the intake manifold, between two direct feed line to the injector.
