ordered the pressure tester but in the meantime just replaced the fuel filter. car has 67,000miles. i got it 1 year ago. at the time i changed oil/filter and transmission. synthetic.
i changed fuel filter just because i didnt know if previous owners have done that. and maintenance schedule tells every 60,000 miles.
am glad i did. all around was rusted; when emptied it, gas flowed very dark.
and when i drove it runs so smooth.... frankly, i didnt expect any detectable change.
will open the old and see how it looks, but expect lots or dirt.
didnt know how important replacing it is.
