How to Replace the Fuel Pressure Regulator on a Celica

Toyota has used the Celica name for a variety of sedans since 1970. The most recent version of the Celica is a 3-door hatchback that was in production from 1999 to 2006. These vehicles have 4-cylinder, 1.8-liter engine with multi-port fuel injection. The fuel pressure regulator in a late-model Celica attaches to the fuel filter and is accessible with an access panel under the rear seat. The replacement of the fuel pressure regulator in a Toyota Celica also requires the removal of the fuel pump assembly.
