fuel filter on 1991 Oldsmobile 98

Where is it located.

Look under the car on the passenger side just in front of the rear wheel. That's where it is on 94,95,96 models. If not there, it might be closer to the fuel tank. The lines and fittings on the filter usually get pretty corroded due to their location.

NOTE: remove the fuel pump fuse and start the car before you change the filter. Let it run till it quits. This is the easiest way to take the fuel pressure out of the line and empty it at the same time. There will be very little fuel left in the filter when you change it.

Be very careful when trying to turn the filter nut. Soak it with pentrating fluid a couple of times and tap the fitting to help the fluid soak into the corrosion. Use 2 wrenches. One to hold the fitting on the fuel line, one to turn the filter a bit. Make sure you don't break the line when you're doing this. Hope you find this helpful.
