Fuel system?

Hi,

I attached a pic below. I circled the fuel pulse damper. Is that the component you are referring to?

Next, if you are getting a lot of thick white smoke from the exhaust, that is usually an indication of coolant getting into the combustion chamber and being burned. Commonly, that is caused by a failing head gasket.

Take a look through this link and let me know if anything mirrors what you experience:

Let me know what you find or if I can help in any way.

take care,
