I'll assume it's the same as the 2nd gen. It's inside the fuel tank and absolutely does not need to be replaced.

I cant imagine they would be so stupid to put the fuel filter in the gas tank.
The pumps all have inlet screens, but i have never seen a fuel filter inside a gas tank.
Look under the car, trace the lines from the fuel pump to the front of the car.
There is typicly a big filter in line under the car someplace.

Since fuel always flows from the pump, to the fuel rail, and most returns to the tank, a lot of fuel circulates through the filter. Very little actualy gets used by the injectors and most returns to the gas tank. Only at full throttle, high rpm's, with a cold engine would get close to using most of the fuel flow to the fuel rail.

Most modern fuel filters are quite large to handle all that flow, the VW filter was good for 100,000 miles (they said) and was about 5 by 3 inches in size.....

Okay, thanks for your quick reply!

The filter is absolutely inside the fuel tank. The 2004 Service Manual, page 11-256, says:

The fuel filter should be replaced whenever the fuel pressure drops below the specified value (see page 11-247), after making sure that the fuel pump and the fuel pressure regulator are ok.

Page 11-247: The pressure should be 330-380 kPa (3.4-3.9 kgf/cm(sq), 48-55 psi)

I haven't found anything that says anything on replacing the fuel filter on a specified mileage basis.

I guess that ties in with the oh so easy to replace cabin air filter...

No, this one is easier to replace. There is an access hole in the trunk floor, so you don't have to pull the tank. Just remove the trunk floor, remove the cover, and then use the special tool (the only tricky part for the do-it-yourselfer) to remove the collar and then the fuel pump lifts right out.

Brettg

Same as the Passat. And the fuel filter is in with the pump?

A picture is worth 10,000,000 words (inflation, you know).

The filter is #5, and the fuel pump module assy is #2.

Number 5 does not look anything like a filter to me, more like plumbing between the pump and the bung. if there is a filter in there, its just a screen, as there looks to be nothing in there big enough to be a real paper fuel filter that is going to hold 100,000 miles worth of dirt.

You're entitled to your opinion, and you stick with the 100,000 mile figure, but at the price listed it is probably more than a screen, and if Acura thought it should be serviced regularly they probably would have told us.

Brettg

Are you sure there is no 'normal' fuel filter under the car someplace?

All the filters I have seen are quite large...

Brett

Ron A

This is the only fuel filter listed in the service manual index, and the picture of the fuel lines doesn't show a filter either.

Brettg

Thanks for the info.
Some sort of crazy setup, I guess the filter is the round thing below the bung top, quite small for something that is placed inside the gas tank.
I wonder why they did it that way.....
