ahh man im not being a smart A but really those 2 install are so self explanatory. take about 1 min for the o2 sensor and about 5 min for the fuel filter. A couple little thing to rmemebr though for the fuel filter, make sure you take the cap off your gas tank before undoing the tubes connected to the fuel filter, and also disconnet the bottom attachment to the fuel filter first and hold the filter up so it doesnt leak.

good luck.

remove the fuse for the fuel pump..crank it over 3 or so times..then undo the fuel filter..replace it with a 91+ 300zx fuel filter~

i got the fuel filter and spark plugs changed.....but the O2 sensor :'( it just wont come out....... i tried to turn it anti clockwise with all my strength..... it just wont turn...... is there any screw or nuts i should lossen before i turn the O2 sensor?

Nope, they just get rusted in there really bad. You can try soaking it in penetrating oil for a couple of hours and if that doesn't work then try heating the manifold. If that doesn't work you're pretty much screwed.

I found a o2 socket ,, I couldn't even get a wrench on mind. ONce I put the socket on an extension it came out too easy...

Well there are tools to take off the o2 sensor. The tool I've got is a 22mm deep socket that has about 1/3 of the side removed so it'll let the wire poke through that. The approximate depth of my socket is about 2.5 inches and you can have it notched around the back so you can slip a open ended wrench around it so you can actually turn the sucker if it's as hard for you to turn it as it is for me.

fuel filter procedure is as previously described, pull the fuel pump fuse and then turn the motor couple times, that should drain the system. Next pop off the bottom of the fuel filter and then the top of it. In the event that not all the fuel or there's some fuel coming out still have some rags handy. Swapping with a 300zx fuel filter is really up to you. I haven't really noticed much difference although it is recommended.

I didnt know I had a fan. Thank you, I am flattered.

Taking the lines off the filter was a b-i-t-c-h when I did mine a couple of weeks ago. Same way on my girl's G20. Any tips on removing them easier?
