Fuel Injection Rail Problems of Subaru Impreza Wrx

When I start my car when it is cold out 20 degrees or below my gas line near the fuel rail leaks on the passenger side of the engine until the car warms up. It leaks a little up to enough to pool on the engine. . It worries me because it is on the turbo side of the engine with the exhaust which temperatures can reach up to 1500 degrees. The car could easily catch fire. It is a known problem in Subaru Impreza Wrx models 02-05 and has been brought to Subarus attention multiple times.

This is in reference to Subaru issued TSB 09-36-03 titled: "fuel smell in cold weather. ". This problem is going to kill somebody unless you mandate a recall. I reported the issue a few years ago and your investigation concluded it was not a serious problem. Since then I've dealt with the fuel odor on cold days. The odor now occurs when the temperature is below 35 f. A couple of days ago, the temps were in the teens f and the odor got really bad. After driving for about 10 minutes, white fumes started pouring out of the right side of the hood and from the scoop. There is so much fuel leaking now that it's being vaporized into a white smoke and spews out of the engine for about 1 or 2 minutes. I opened the hood to confirm there is no fire, which there was not. But there was an impressive amount of white fumes which resembled smoke but again, no fire. A friend who was driving in another car, 3 cars behind me, reported that the gas smell from my car was so bad they had to pull back. After doing some research, vaporized fuel will ignite at 536 degrees f. It is very possible for the turbo charger on this car to get that hot after some driving. With the engine compartment full of white gas fumes and the cabin fill of a powerful raw gas smell, it only stands to reason that this could catch file in the engine compartment and the passenger cabin. After doing a simple search on this (odi) website for both Subaru wrx, and Subaru impreza, looking at several different categories (fuel system, fuel delivery, fuel rails, ect) I found 286 complaints of the same problem. .

I want to report a fuel leak in a 2004 subara Impreza Wrx. The leak is occurring due to a loose hose clamp along the fuel rail near the manifold (driver side). The leak only seems to occur in cold weather (<20 f). You can visibly see the leak. In one week when the temperature was near 10f (for the entire week) I lost nearly 1 gallon of fuel during a 5 day span where I drove only 270miles.

I own a 2004 Subaru wrx with 42000 miles. It was recently below 20 degrees in town and I noticed a raw gas smell coming from the engine compartment. Upon further investigation I pinpointed the smell was coming from under the air intake manifold on the passenger side. I have taken the car in for diagnosis from gallas and davis Subaru in albuquerque. They confirmed gas leak coming from fuel rail. Dealer has quoted 670. 00 for repairs. I have seen Subaru released TSB 09-36-03 relating to this issue. I am waiting on response from Subaru of America to see if some or all of the repair cost will be covered. I was told by the dealer to close the vent and I would not smell the gas. I was also told by soa that the issue is only related to 02 models but have found evidence stating otherwise as all fuel rail lines are the same on 02-04 model. The replacement parts related to TSB 09-36-03 fits all the same year models.

Fuel leak on 2002 Subaru Impreza Wrx. Fuel leaks/sprays form fuel lines onto manifold. Strong fuel smells fill cabin with vapors. Possible chance of fire in engine compartment. Contacted Subaru with no resolution. Find this to be a very common problem with 2002 Subaru Impreza Wrx.

Smell of raw gas fumes in the passenger compartment of vehicle and under the hood of the vehicle at temperatures below freezing. Took the car to the dealer and they quoted a $500. 00 estimate to "repair leaking fuel lines below manifold". They told me not to worry about it-"it won't catch fire"!!!.

My 2002 Subaru wrx suffered the cold start fuel leak problem described in the TSB (fuel rails). Vehicle was purchased used from dealership, but dealer did not address the problem while vehicle was still under warranty.

I live in maine and in cold weather my my 2002 Subaru Impreza Wrx leaks fuel from a fuel line on the passenger side of the vehicle. Subaru of America has issued a technical service bulletin for this problem.

1. Fuel leaks from the fuel rail when driving in cold weather. 2. Fuel leaks from fuel rail and rubber fuel line that is positioned under the intake manifold while operating in cold climate. This condition causes fuel to leak on to the hot engine causing smoke to rise from under the hood and possibly ignite raw fuel, it also causes the passenger compartment to fill with a strong gas smell. 3. Correction-replacement of fuel rail and rubber fuel line as indicated in the car makers service bulletin. Old part not available.

There is a rubber fuel line linking the injector fuel rail to the hard steel fuel line leading from the fuel tank, that contracts at a different rate than the fuel rail nipple. This causes a fuel leak on the turbo side of the engine. This is a problem that Subaru and it's dealers are well aware of as it happens on the 2002-3 Subaru wrxs in cold climates. The most alarming aspect of this is not just a leak, but the leak is on the turbo charger side of the engine. The amount of heat in the turbo would ignite vaporized/liquid fuel rather quickly. To me it is really amazing that these things are not bursting into flames all over. The company is also charging their customers for the fix, which is expensive, to a problem that is clearly their fault. Not to mention that leaking raw fuel is an environmental problem.

Vehicle is leaking fuel into the engine bay. The passenger side fuel rail is leaking. Subaru of America is not willing to fix the issue it is happening to a lot of people. The vehicle has gasoline fumes coming in through the vents. The condition is worsened in winter.

In cool or cold weather, there is a very strong odor of raw fuel inside the passenger compartment. Anyone inside or near the car is exposed to harmful gasoline fumes, these vapors are toxic when concentrated and may cause dizziness and hallucinations in smaller amounts. There is also concern of potential fire danger. Fuel odor has been present year-round on my car, and also on many other 2002 and 2003 Subaru imprezas. This is a common issue that Subaru needs to address, but their position seems to be that it is the customer's fault and responsibility. This repair, to correct a design flaw in the Subaru wrx, will cost the loyal customer several hundred dollars. Thanks Subaru, thanks a lot.

(1) events leading to problem: while traveling from seattle wa to sun peaks bc, temperature on bc5 hwy reached -27f. (2) failure and consequences: under these circumstances one of the joints connecting a fuel line to an injector started leaking fuel into the engine block. I only noticed this condition based on a very strong smell of fuel each time I stopped the car and by close visual inspection of the injector fuel lines -- I noticed fuel was dripping -- in order to avoid the risk of fire, I had the vehicle towed to select auto of kamloops (Subaru dealership). I could detect the condition myself and put a post-it for the Subaru dealer. The condition did not repro at normal temperature (above 0f), so the mechanic had to spray freon on the injector lines to repro the failure. I think that the problem is a major one as it (a) entails the risk of getting a fire on the vehicle. (b) is difficult to repro. (3) fixes done to the car: replaced rubber line and clamps.

There is a fuel leak on from the fuel rail when its cold out.

To whom it may concern. I own a 2002 Subaru wrx, and when the weather is cold, I get a very intense gasoline smell in the cab of the car. Reading on the Subaru forums, it seems that this problem is happening to a lot of other Subaru wrx owners, some of which have gotten it fixed under their warranty, but most of us have no more warranty left. I have gone to my local dealer (ogden Subaru) about this problem, and he treated me with such disrespect that it outrages me. He also told me that the labor to fix this problem was $450 dollars, and the parts are $350 dollars. Then he proceeded to tell me that I was using the wrong octane of fuel, and I was "revving" the engine when my car is cold, which is !@#$% to begin with. I know that this is a manufacture defect from too small of fuel hoses on the fuel rail, and I know that this is a safety hazard from the fumes of the gas in the cab of the car, so why the !@#$% is there not a recall on these parts? to let you know what im going through, I have to drive to work every day with my rear windows unrolled to get the fumes out (I live in northern utah, there is 3 feet of snow on the ground), and I cannot turn my heater on because it vents more gas smell into my car. They say that gas is not as flammable as the vapors it gives off, how long am I going to have this hazard before the problem is fixed? on a more personal note, to hell if I am going to pay for a repair for a part on my car that is not my fault at all, yet its a manufacture defect. I really don't want to get a lawyer involved with this situation, but if I have to, I will, and im sure he will be as outraged as I am. -erik p. S. This problem has been going on with myself and with many other Subaru wrx owners, I think its time we get this problem fixed.
