Hey all,

i bought a 180B fuel tank from a member, he also supplied this...thing...with it. Is it something to do with emissions? how do i plumb it up?

Cheers.

Something to do with the breather. I got one one on my 180b aswell. It mounts under the parcel tray.

Breather line from engine runs to the middle, the other right angle connection runs into the top of the tank and the connection on the side runs to the filler neck.

Had one in my SSS when I bought it. Yes, I think it's something to do with emissions controls as the earlier SSSs didn't have them. I reckon it's something to trap petrol vapors, condense them and allow them to return to the main tank. Bottom line: unless an engineer of the EPA insist on it (unlikely if you don't have a late 180B) you don't need it.

Cheers!

im hoping to use it now, instead of using a charcoal cannister. only for sole reason of engineering

Charcoal cannisters are not an ADR requirement on a 1600.

They are if you have a fire breathing polluting FJ in it

Not in SA. Our regs are hard. But they stick to the ADRs IF your engineer points it out.

Are you able view an official document that states that it is a requirement?
If so. I would like to see a copy please.

Needs a charcoal canister mate, EPA will laugh at you if u dont

What's the logic behind needing one on a 1600 ? They weren't fitted when new, and aren't a part of the engine emissions equipment for the later model engine ?

i asked the engineer to supply the document which states i need a cannister, when fitting an FJ20ET to a 1971 Datsun 1600. this is what he sent me.

So, subsection a) isn't applicable, you're not removing or making ineffective something required by the ADR's for a 1600, as they didn't require a charcoal canister.

Subsection b) - must meet the intent of the ADR's applicable to the later substitute engine. The charcoal canister isn't something that is "applicable to the substitute engine", it looks after fuel vapours from the fuel tank. It uses the engine to take care of this, but the emissions from the engine aren't effected by the presence or otherwise of the charcoal canister.

The sentence about "the functional elements of the noise and gaseous emission control system of the donor vehicle" could possibly be construed to include the canister, I guess, as that does control "gaseous emissions". Personally, I would argue that the intent of the document is for the "gaseous emission control system" to relate only to the "gaseous emissions" of the engine.

At the end of the day, I guess it is an easy / cheap thing to fit (and easy to remove later ), so is it really worth the effort to argue the point (and possibly upset your engineer) ?

the whole point of this post was to see if i could substitue a canister for the original parts shown above. never to not fit one.

If you take what the engineer sent you to mean you have to fit "the gaseous emission control system of the donor vehicle", then I would say you need to fit whatever an FJ20 came with, if the "donor vehicle" used a charcoal canister, you'll need to fit a charcoal canister, not something else from a 180B that may or may not be a charcoal canister.

The thing is listed in the spares manual as an "Assembly. tank reservoir" and is peculiar to Australian 180B's manufactured from Sep 74 onwards.
