Unscrew the plug and pull it straight down so it will clear the fuel tank outlet pipe.

To replace the fuel filter in fuel-injected models from 1990 through 1999, relieve fuel pressure, secure the fuel filter upper fitting with a wrench, then loosen the upper banjo bolt, removing it along with the gaskets and high-pressure hose. Secure the lower fitting, loosen the lower banjo bolt, remove it with gaskets and the fuel main hose. Remove the filter mounting bolts and the filter from the firewall. Install new gaskets on each side of the hose fittings, place both hoses onto the filter, and tighten the banjo bolts to torque.
