Look under the car, just in front of the fuel tank on the passenger side.
where is the fuel filter located on a 2003 Pontiac sunfire
there is a filter in line and a sock filter on the fuel pump in the tank!
In the 2001 model year Sunfire, the fuel filter is located at the rear of the car, just behind the fuel tank about in the center of the car. Model years will vary, but it will be in the general area, with some years being forward of the fuel tank just off to the left side.
You release it by taking off the fuel filter. Be sure the ignition key is off. About a half cup of fuel will spill.... more if you encounter a siphoning effect.
In the fuel tank
Under the car by the fuel tank
Follow the fuel lines forward to the engine from the fuel tank. Somewhere on the line you will find the fuel filter.
Try back near the fuel tank. if it is the same as my sunfire it is right behind the gas tank.
it at the back of your gas tank
next to the tank
The fuel filter on a 2002 Pontiac Sunfire is in the rear between the fuel tank and the rear axle. By the way its under the car and easy to change takes about 10 minutes.
I know that on a '96 the fuel filter is an in-line type near the fuel tank. As Pontiac hasn't really altered much on the Sunfire in over ten years, I'd suggest starting there.
