Toyota Tercel 1984-1994 Repair Guide

Fuel Filter

Print

The replaceable fuel filter is located in the fuel line, either mounted on the firewall under the hood or located at the rear of the car near the tank.

The filter should be inspected for external damage and/or leakage at least once a year; it should be changed at the proper intervals or more often under dry, dusty conditions.

Removal and installation procedures differ slightly for each year and application.


CAUTION
Do not smoke or have open flame near the car when working on the fuel system.

Fuel Injected Engines

CAUTION
Safety is very important when preforming fuel system maintenance. Always perform this service operation on a COLD engine. The fuel system is under pressure - fuel pressure must be released before removing the fuel filter. Failure to conduct fuel system maintenance and repairs in a safe manner may result in serious personal injury.

  1. Disconnect the negative battery cable. Unbolt the retaining screws and remove the protective shield for the fuel filter (if so equipped).
  2.  
  3. Place a pan under the delivery pipe (large connection) to catch the dripping fuel and SLOWLY loosen the union bolt to bleed off the fuel pressure.
