I am very surprised that the 04 cars dont have a servicable fuel filter...

How high do you need to lift the car in order to drop a fuel tank?

Since this thread is really old, and recently revived, I'll just throw in an "FYI"....

My car is an '01, with low mileage (22K). I changed the OE filter when the car was about 4 years old, "just because". In other words, preventive maintenance.

Last summer (2012), I started smelling gas after the car was shut down. Then one day, while driving, I smelled it again. Although I didn't originally see any drips, as soon as I got home from my drive, I ran the car up on the ramps and started looking. I noticed the filter outlet side was dripping. Apparently, the ethanol content of the gas had attacked the o-ring on the filter, as simply replacing the filter cured the problem. Good thing, as the fuel line runs right over the LH side exhaust pipe....

Shouldn't be. It IS awkward, especially if you're on ramps, and not on a lift, but not impossible...

Replace as needed

My previous '01 C5 had over 200,000 miles on it and I never had to replace the fuel filter. Granted I always did use Chevron gas religiously which probably helped. I would recommend to replace it only if needed.

Just asking.....

The only indication I had was a slight reduction in gas mileage from 23+ to 22 average mpg; but that could have been from aging engine parts too. So if the fuel filter is partially plugged but still working, why change it?

Could the Techron bottle treatments and Chevron gas be breaking down the minute debris and allowing it to get past the injectors and be burned in the combustion chambers?
