Fuel Filter replacement

Time to replace mine, and I have no idea where it is. The dealership's schematic was just about useless and they suggested just following the fuel lines from the engine to the filter, but that sounds like a real PITA, especially if the lines are up in the floorboards somewhere (as I suspect they are). Anybody done this one before?

Also, can I pull the fuel pump fuse and let the engine run down to relieve the pressure in the lines like I used to do on my LT1 Imapala? And which fuse is it?

Thanks in advance! :)

The fuel filter is located to the inside of the left rear tire, in between the frame and the transmission. Hope this helps.

I hear you don't need to replace the filter unless you experience problems. How often are others replacing their filter ?

Re: Fuel Filter replacement (newride)

The filter runs about $60 at the dealer, and has the regulator incorporated in the design. If you jack the rear of the car, you can change it by sliding in on your back. As was already mentioned, the filter is on the drivers side, just forward of the rear wheel, in the tunnel abreat the transmission - you can't miss it.

I did not relieve fuel pressure when I changed mine (no Zeus fitting with the Magnuson fuel rail), and didn't have any problems. You will need the special fuel line release tool for the output line (a little doughnut shaped plastic thingy). It has to be the proper size or you will never get the output line off.

The input line and fuel tank return line are easy to get off, you just have to release the blue fittings. Remove the ground strap with a 10mm socket.

Have a rag handy or you will take a gasoline bath. Actually, you will take a gasoline bath either way you do it, so wear eye protection.

It is a 15 minute job, including jacking the car. If you have an automatic, it is a little more difficult, as you may have to drop the drivers side over-the-axle exhaust pipe.

I believe that the C5 fuel filter doesn't need to be changed until the car reaches the 50,000 mile mark, is that so?

Re: Fuel Filter replacement (TwoTonSS)

Sounds like money well spent to have someone else do the job. I would probaby wind up with a major fuel bath.

According to my dealer, it's reccommended as part of the 30,000 mile service, as well as a fuel injector flush, oil change and plug change. I figure I can do all this myself and save the astronomical rates they charge.

Re: Fuel Filter replacement (TwoTonSS)

Dealers and iffy lube joints are forever inventing, or recommending, maintenance in order to increase profit but those schedules not the ones that GM lists for your car.

I'd suggest reading page 7-9 of your owner's manual before you waste any more of your money.
