While driving an increasing smell of raw gasoline was noticed in the vehicle. Upon investigation of the fuel pump located under the passenger seat behind the driver's seat there was an accumulation of gasoline below the fuel pump outlet to fuel line coupling. Upon removing the fuel line coupling and the fuel line going to the engine it was observed that there was a crack approximately 1/2 inch long in the bottom portion of the plastic fuel pump outlet which had allowed gasoline to accumulate on top of the fuel pump housing. The fuel pump along with the fuel line going to the engine were both replaced which corrected the fuel leak problem. It would be recommended to check for cracks in the fuel pump outlet the next time this type of vehicle is brought in for service.
Hello. How are you? I hope everything is going well for you. I am an owner of 2005 Mazda rx8. I was a faculty of one university at texas by 2016. However, I left USA last fall and currently settled down in Korea. I also took my car (2005 Mazda rx8) from USA to Korea. In terms of safety recall notices, I asked Mazda USA to solve two safety recall issues (Mazda recall #: 1017e—fuel tank leak as well as 9416e—Takata recall) for my car. Unfortunately, there are no Mazda dealer shops in Korea, so I asked to Mazda USA to send the parts via the mail to replace bad parts for my car. However, they rejected my requests and they said only Mazda (certified) mechanic should complete the repairs. I am wondering if I can solve these serious safety recall issues. Am I not a customer of Mazda because im not staying in the us anymore? …
