Default Fuel Filter Replacement

I've change many fuel filters in my life but I've never attempted one like this (2001 Conv). The manual talks about the use of a special tool needed to remove the metal collar from the outlet side of the fuel filter. This is new to me the other two inlet lines are held together with a plastic collar which I'm familiar with. My question is, do I really need that special tool or is there another way? Has anyone here replaced a fuel filter like this? Any help? I don't want to screw anything up before I continue. I just can't believe it would be that difficult.

You will need the fuel line separtion tool to get the outlet off. You can get a whole set at the autoparts store for less than $10. The rear 2 you just squease with your fingers and pull off. Be sure you get an AC delco filter as it also contains a pressure regulator. Some of the after market ones I have been told do not. I believe that I paid about $45 dollars for the one I got.

IMO...it is ALOT easier to have someone else do it. I paid EZ-Lube 20.00to do it, I watched them like a hawk. They have all the tools, and it beats jacking the car and getting gas all over the place.

Thanks for the info! That's what I needed to know. I purchased a AC Delco filter from Summit which is a OEM replacement. It's alway something huh? I remember the old days when it took just two hose clamps.

Hey Reb.....anything I need to know when using that tool? The manual says something about pulling the sleeve up first.

I replaced my filter with the car up on jack stands. It wasn't very difficult, except for figuring out how to use the tool properly in the small space that is available. It helps to remove the aluminum cover on the lower rear section of the left hand side fuel tank to gain more room. If you do it yourself, remember to relieve the presure in the line by depressing the Schrader valve on the fuel rail. If you don't you'll get a good soaking of fuel when you release the fuel line from the front of the filter. This could be a big problem if you happen to have a hot shop light under there with you.

Shop manual says to pull the fuse for the fuel pump, then start the car to run out the pressure. Avoids getting gas in the engine compartment. Or get a pressure tester. Good thing to have - used it more than I expected, and it wasn't too expensive. Bought at Sears.

The separation tool is just a little plastic ring that you snap over the fuel line and then press into the filter. That spreads the fingers in the filter out and you can just pull it off.

You do need to relieve the pressure on the line. Take off the drivers side fuel rail cover. You will then see a plastic cap at the end of the fuel rail. Remove that and press in the schrader valve to bleed off the pressure. Put a rag under the valve to catch the fuel.

There are a couple different tools to take off the fitting. One is a metal fitting made of aluminum that splits apart. The others are cheap throw away plastic types.

Just put the seperator in the fuel line as far as it will go, push the fuel line towards the filter as if you are pushing on, then slip the seperator in a little further, then pull it off.

The presence (or lack of) a pressure regulator in the filter has nothing to do with it being OEM or aftermarket. It strictly depends on the year model. Getting the correct model year is the most important thing.

I'm a new member and I can't figure out how to get a question submitted. Please help if you can. How often should a fuel filter be replaced in a C5 and C6? Txs!

On the C5s there isn't a factory recommended interval. As a general rule, I'm seeing most guys (me included) go with a 50K-60K changeout period. I can't speak to the C6s, but I suspect it's the same for them.

HTH,
Robert
