Yes.
There is no fuel filter external to the fuel tank.
Whether the cost of replacing the internal filter is worth it, that's
your call, not theirs.

___________________________
The reason I asked is because my actually mpg(city or highway) doesn't
even come CLOSE to this:

http://consumerguideauto.howstuffworks.com/2004-to-2007-chevrolet-malibu-4.htm

Under Powertrain Options second row: ohv V6 3.5 / 213 200 220

I don't even top 20mpg on the HIGHWAY, let alone "23 city 32 highway"!

I had a UTH fuel injector cleaning, the tires are inflated to
31psi(door panel says 30psi). They are "H"-rated Yokohamas and will
ride too harsh if I go more than 1-2lbs over factory recommended
pressure, and I replaced the air filter 1,000 miles ago.

Frankly this car never got more than 20 city and 24 highway when I
bought it new, but this is ridiculous.

So I'm trying to think of everything. The alignment was done last
September and is fine - car pulls slightly to the left even with front
camber set up to pull to the right, but car rolls forever when I let
off the gas, especially in city driving.

My trunk has only 20lbs worth of toolkit in it. So my issue really is
what is causing my car to average 10mpg lower than what it potentially
could achieve in fuel economy?
My old 2003 Impala averaged 24mpg on it and was a bigger car.

All the Malibu V-6's (lots) I have rented got at least 22 mpg in hard
city and mountain driving.
On the freeway they got at least 26 mpg.
At only 22k miles its unlikely one of the O2 sensors had burned out, but
I would have
that checked. Also, have the fuel pressure regulator checked.
Better do those before the cat burns out and causes major problems.

Wouldn't O2 issues trigger a "check-engine" on the dash?
