Jack up the rear of the car and put it on stands, lay down under the car with your head just forward of the fuel tank, look STRAIGHT up.

That little metal canister with the hoses going to it is your fuel filter.

You'll need a quick-disconnect tool and a flat-blade screwdriver to change it out.

Yes! It has been found and replaced! A shop wanted $50 to do it. It took me 3 beers 30 minutes and a $10 replacement part so its a sucess NOW my check engine light comes on??? bugger It seems my O2 sensor is the original one from 1991 I'm told that it has to be blowtorched out with the exhaust header off??? I've tried everything but that it will not come out. Is this correct info any other tricks? I don't have a torch Thanks again!

Soak the heck out of it with PB Blaster, let it sit overnight, tap all around it with a ball peen hammer, hit it with PB Blaster again then use the proper socket to remove it.........................
