idle, change it.

Your mechanic is obviously a "general" mechanic who has very little Toyota specific experience. His 12K advice is good advice for American vehicles which have a reputation for developing expensive fuel injector problems if the fuel filter is not changed frequently.
But Toyotas are different. A 50K fuel filter change interval is sufficient to keep the fuel injectors clean for over 500,000 miles. I'm at 472,000 miles so I know this to be true from first hand Toyota specific experience.
However, most late model Toyotas don't have an accessible fuel filter anymore located on the fuel line. Some depending on the year and model of your Tundra, you may not have an
accessible filter, just one inside the gas tank. Gas tank fuel filters don't need changing for at least 100,000 miles.
