They still get clogged like any other filter. If they didn't, there wouldn't be a need for them in the first place.can't think why you'd need to change a fuel filter on a petrol car anyway !??? unless its done starship milleage ! is the fuel quality in the states really that poor ?!
The fuel filter on my 2004 e65 745I is located on the Drivers side right under the drivers front seat. When you remove the panel under the car, (4) 10mm plastic nuts and about (12) 8mm screws you'll see it. Just remenber the fuel filter is under pressure and it will spray fuel all over if you don't release the pressure before you remove it!It is underneath the car -- near the area under the front passenger seat (on the underside of the car). Your mechanic will need to put the car on the lift, remove some panels on the underside to gain access to it. He should have no problem changing it once he finds it.
