Where is the fuel pump and fuel filter at - 1992 Buick LeSabre

The fuel pump and strainer are located inside the fuel tank.

There are three possible locations for this component due to different production dates/locations: under hood, passenger side, rear engine area, below firewall, mounted in fuel line or under vehicle, passenger side, below seating area, mounted on frame in fuel line or under vehicle, driver side, below rear seating area, mounted on frame in fuel line

Easiest method to find, follow the fuel pump lines from the tank forward, you'll find the filter.

If you change the filter, it's not a bad idea to put a little Gumout fuel injector cleaner directly into that new filter, about 1/2 full before reinstalling, that will give your injectors a quick clean. It can cause a short sputter or two but I've never seen it cause a problem and it does help clean the fuel system quickly.

You'll also want to remember to turn the key on for 3 seconds, off for 3 seconds, alternating until the fuel pressure builds before trying to start the vehicle, after repairs are made to either the pump or the filter.

Use caution when removing lines, pressure and flammable !

Good Luck
