Fuel Filter Change

[david-b]

Hey all;
Decided I should change the fuel filter. Never done it, and dont know when it was done. Question: Where is it? Is it in the backseat? I lost my Haynes Book. Thanks.

Oh, and is it hard?

Under the battery and intake pipe on your car. According to all data anyway.

Oh i could go on for days about that....apparently the firing order on a GM 5.7 is 1-2-3-4-5-6-7-8..... Not exactly the greatest technical program, good diagrams though.

I shouldve searched before posting. Found it within 2 seconds. Duhh. How epensive are fuel filters, and can I get one at AutoZone? Also, do I have to relieve the fuel pressure beofre doing? Thanks

Fuel filters are about $20 at autozone. You might want to relieve the pressure to prevent a lot of gas pouring out of the fuel lines but you could always just get a cup or bucket to catch it in. If you go by the book you have to have a fire extinguisher handy too. Changing the filter is actually pretty fun and if it is bad you will notice a great change in your car's performance.

Is alot of fuel going to pour out? I would imagine because of the fact that the car is not on, that it would just be whats sitting in the lines. Is that alot? Fire extinguisher myass. Although it would have been nice when my car caught fire when I first bought it.

How would I relieve the pressure? Then, how would I get the pressure back? Thanks

Remove the fuel pump relay, and depressurize the fuel rail, that should take care of it. Once you put the relay back on and cycle the key it will pressurize again.

How do you depressurize the fuel rail? I know this is probably basic knowledge, but I've never done it. It would also be good for people who search on this in the future. Thanks

Disconnect the fuel pump electrical connector.
Start the engine and let it run out of fuel.
Turn it over to make sure it does not start.
Done

[david-b]

Wouldnt letting the car run out of fuel cause it to possible mis-fire?

And that will run the lines dry? Then disconnect everything I need to and Im ready to go?

[SLoe]

It will only take a few seconds. You aren't going racing ; )

There will still be a little bit of fuel leakage, but you won't get sprayed in the face this way.

Just let the gas leak a little bit it's not much and it's gonna leak a little no matter what so why go through the touble? You might want to get a 14mm flare wrench for the bottom bolt.

You know I've done this a few times and the manual says that your car will die but I have let mine run for like ten minutes and it never died. I still didn't have a lot of spillage anyway.
