How often to change the fuel filter
There is no set period for changing the fuel filter on a 2002 Montana. However, it is recommended to change the filter after 12,000 to 15,000 miles as part of routine service maintenance.
The only time you should have to change the filter is if you have allowed it to run completely out of gas and you suspect the fuel system to be contaminated. In addition, if you drive in dusty or sandy conditions, you should change your filter more frequently.
GM vehicles tend to need the fuel filter replaced more often than other brands. It is recommended to change the main filter when there is around 10% life left.

How to access the fuel filter
The fuel filter on a 2002 Montana may be located on the underside of the vehicle, in which case you will need to jack up the car to access it. If the fuel filter is located on the bottom of the car, it will be just past the fuel pump.
In some vehicles, the fuel filter is located in the engine bay on the line that leads to the fuel rail. In others, it is located underneath the hood, near the engine. Certain vehicles have the fuel filter located in the fuel pump, along with a filter screen that’s inside the fuel tank. The fuel line might also be located running against the frame rails underneath on some cars.
If you can't find the fuel filter, refer to the owner's manual. You'll also be able to determine if your vehicle has more than one filter.

How to connect the quick-connect fitting
Quick-connect fittings allow you to connect and disconnect tubing without the need for tools. They are comprised of three individual components: a collet, an O-ring, and a body. The body of the fitting conceals the O-ring and collet on either end. Your tubing is meant to be inserted through the collet, through the O-ring, and into the body of the fitting. These three components create a water-tight seal. As pressure increases inside the tubing, the water or air forces the collet into a groove on the inside of the fitting. The grooves compress the collet so that the little teeth on the inside of the collet dig into the tubing, making it virtually impossible for the tubing to disconnect.
To connect the quick-connect fitting at the outlet of the fuel filter of your 2002 Pontiac Montana, you should first ensure that the system is depressurised. Then, push the collet squarely against the face of the fitting. With the collet held in this position, the tube can be removed. The fitting can then be reused.
