Change fuel filter

I have a 1994 Sentra that I am using to learn car repair. I have done full new breaks, gaskets, sparkplugs/wires, distributor/rotor, PCV valve, ect. already.

I am going to replace the fuel filter now but I read that I need to relieve the pressure on the fuel line before I disconnect the old fuel line. The process has something to do with putting the keys in the ingition, but beyond that I don't know.

Can anyone tell me how to take the pressure out of the fuel line (and then put it back when I am done :) ) I need to not die in the process so any safety tips are appreciated.
Also, does anyone know if Nissan put this filter under the hood or below the car between the tank and the engine?

Thanks guys! and yes I am a new member.

It should be under the hood between the engine and the firewall. And all you have to do is take off your gas cap off before you remove the filter. Don't worry too much about all the pressure stuff.

1.remove gas cap
2.change filter
3.replace gas cap and go

Sounds good enough to me. Now I just need to find the darn fuel filter. Cars with 170k miles seem to all be the same black color under the hood.

Is there any stratification amoung fuel filters? I mean are there some that are to be avoided or are they all pretty much similar?

meh, they're all the same. Avoid "performance" filters(yes, I've seen them), you don't want crap coming through your line for the sake of slightly free-er flowing fuel.

Thanks for the quick reply. I will go by autozone tonight and get whatever they have.

Also, how often do you change your tank filter?

Tank filter? Shouldn't ever have to change that unless you score over a quarter million miles on your car.

Great help so far. I really appreciate it.

I have been giving my car a tune up and I wanted to make sure that I didn't pass over anything obvious that it needs. It has 170+ miles and no tuneup for at least 30k. I have just given it new plugs, plug wires, distributor cap, rotor, valve cover gasket, pcv valve, and fuel and air filters. I am going to have my alignment done at a car shop.

Anything else that I should do?

oil change

haha

oil change

Ok, you burned me good with that one. I still have 2k miles to go before I need another oil change though.

Actually the best way to remove fuel pressure from the lines is to take out the fuel filter fuse (up by battery) and then start your car. Once it stalls crank it a few more times. And maybe it's because I'm just picky, but I only use Nissan fuel filters and would definately use Nissan oil filters. Don't buy Fram, they are shit and have been proven to be so.

close, its actually you remove the fuel PUMP fuse (upper left corner of fuse box) and run the car til it dies.

I had to actually start the car first (with the fuse in) to get it to start. Then pulled the fuse and restarted until it died (took less than 3 seconds). Pressure relieved.
