"If there is one fuel line running from the tank to the fuel pump, your car was setup for a mechanical pump. They are dependable and should last for years. The main thing with these pumps are what the diapham is made of and what fuel will not bother the material. We are getting into more fuels like E85 and this is having issues with some pumps and lines. This is why most auto companies have gone to plastic fuel lines. "
What does this exactly mean? I've been told to stay away from mechanical pumps because the inner diaphram could break or wear out and leak fuel into the
oil system and by the time you realize it, its too late.
