Where is the fuel pressure tester port on 1997 Toyota Camry?

The fuel filter is located on the driver side behind the airbox assembly. Local parts stores rent a Fuel Pressure test kit that contains a fitting that adds a port to the top of the filter. Easy to use but you have to remove the entire airbox assembly. Filters are cheap and should be changed every 30,000 to 50,000 miles. Good Luck!
