Replace the fuel filter every 30,000 miles to prevent fuel pump failure
It is recommended that you replace the fuel filter on a 2003 Cadillac Seville every 30,000 miles to prevent fuel pump failure. This will help to prevent undue strain on the fuel pump, which can cause the engine to stall and not restart.
The fuel pump may fail if the car has sat unused with gas in the tank for more than 3 to 6 months, so it is important to drain the gas and replace the fuel filter if this is the case. If any foreign fluids, bad fuel, or water enters the fuel system, the fuel filter should also be replaced.
Additionally, if any work has been performed on or in the gas tank, the fuel injectors have been cleaned or replaced, or there have been any major engine repairs or replacements, a new fuel filter should be installed. Leaks at the fuel filter connections might also necessitate a new fuel filter, as well as new O-rings in the push-on connections.
The average cost for a Cadillac Seville Fuel Filter Replacement is between $91 and $110.

If the car has been unused for more than 3-6 months, the fuel filter should be replaced
If your 2003 Cadillac Seville has been unused for more than 3-6 months, the fuel filter should be replaced. This is because gasoline is perishable and will eventually degrade into compounds that will damage the fuel system.
Technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump. If the fuel pump has been replaced, work has been performed on or in the gas tank, or the fuel injectors have been cleaned or replaced, always install a new fuel filter. Major engine repairs, or engine replacement, also require a new filter.
Leaks at the fuel filter connections might necessitate not only a new fuel filter but also new O-rings in the push-on connections to the fuel filter. Diesel-powered vehicles may be equipped with a water-sensor warning light circuit to signal the driver if excessive water has accumulated in the fuel filter.
The most common reason to change the fuel filter is your vehicle’s maintenance schedule, which may specify a filter change interval.
