Hello to all, my Rx-7 of the 93 has 9 years and 45,000 miles. They think that it would have to change to the fuel lines or that it would have to hope to that some flight existed. If they think that if, as it would be the best material, since I have read that the silicone with the tubes of oil and gasoline does not work as well as would be possible to hope. The change by tubes OEM. Some recommendation to leave my car more affluent. I already changed the thermostat, the pump of the water and the clutch.
Excuse me by my bad English
