Three problems related to fuel injection rail have been reported for the 2004 Subaru Impreza Wrx. The most recently reported issues are listed below.
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.
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.
