I bought a new fuel filter for my new (to me) 80' 911 SC. It appears to be quite well tucked away in the back left of the engine bay. Is this something that I can replace myself with normal tools? What tools are required? From what I can see, a wrench is all that's needed but maybe I'm missing something. Don't know how I'll get a wrench into that tight space though.

Also, I failed my emissions test with too high CO, (carbon monoxide) Could a dirty filter be partly to blame?

Thanks,

Nix,

You can certainly change it yourself. As I recall, you'll need two wrenches, perhaps 15mm and 17mm? put a cloth underneath to catch the gas that will come out. Make sure the arrow for directional flow is the same on both old and new filters (I once got a Porsche filter than had the arrow showing flow opposite what it should be!). Undo the strap holding the filter in, undo the top and bottom nuts, replace, tighten it up, done!

Cool, thank you very much! How much gas comes out?? You were able to get in there with regular wrenchs? Your car is 13 years newer than mine, maybe the layout changed a tad?

Sounds exactly the same as mine. I had about 1/2 of a cup of fuel come out when I undid the lines. Easy 15 min. job. Open ended wrenches are all you need.

Awsome, thanks for the help guys!

Nix,

I had a 1981 911SC before my current ride. If you haven't already, you may find some good reading in the 911SC FAQ at tech.rennlist.net.

Make sure the engine is cold when you do this. Best thing to do is leave the car over night and do the fuel filter in the morning. You do not want any fuel pressure in the lines when you loosen the lines.

As for failing the emissions test, the filter will most likely not help. I think leaning the fuel/air mixture would be better. You might want to take it to a Porsche expert and have him adjust the mixture.

Yeah, I believe I am running a bit rich. My car sat for a couple years and it was tested only a day after getting it out of storage. I'm going to give it a few weeks with the new fluids and filters and try one more time (it's only 22 bucks for the test) before I take it to a mechanic.

Any idea what something like that should cost to adjust?

Does leaning the mixture affect hp?

Thanks,

Nix

I thought Canada had a 20 year exemption? Do you have to smog it because it sat unregistered?

Should always have a clean filters, gas, oil, and air.

Apparently not It's not a Canadian thing, it's provincial (BC)
