Where is the fuel filter located on a 1993 Honda A
Ccord LX

I believe this vintage had them on the firewall, left side as you face the car. You Tube would probably have a good tutorial on replacement.

Against the firewall on the drivers side if I remember correctly.

Firewall, passenger side. Look for incoming and outgoing lines, along with a brass "banjo" bolt. Disconnect battery and remove gas cap, prior to removing old fuel filter. Be sure to use a 14mm flare nut wrench to remove and tighten the incoming fuel line (apply Teflon tape to nut). Tighten the banjo bolt 16 lb.-ft.
