Default Charcoal canister / filter

Ok, please don’t quote me on this but my GUESS is that it’s a Charcoal Filter that does something with excess fuel vapour before it’s released into atmosphere or routed back to engine via inlet manifold. .

I could be completely wrong (I’m new here too so expecting to be told as much!) but that’s what it looks like to me.

Might be worth reading up on Volvo charcoal filter to see if they gives you any more clue.

Good luck

Oh and if you need one I’m breaking a full 2.3 240 GLT lol 😂 so check my other post for pics

Good guess, SwedishScotsman.

Looking at the photo and at the OP's location it probably is something to do with emissions; if the OP's car has a B230K engine it's part of the EGR set-up.

I'd also second the opinion it's part of the charcoal filter system. Would be unusual to find it on a 240 GLT as they were always K-Jet as far as i've ever known and lack the ECU to control the valves to admit the excess fuel vapour held in the charcoal filters for burning off during cruising.

I would guess the OPs engine is a B230F (LH2.4 injection) to control it or as Loki suggested, a B230K with EGR.

If you look on the timing belt cover, it should have the engine code on there, you'll probably also have Lambda Sond on the radiator grille and if so, it's LH2.4, if not and no sign of a cat, Lambda sensor or grille badge, LH2.2. Not forgetting of course it could also be K-Jetronic.

According to my red Haynes the EVAP system stores vapour from the fuel tank in the charcoal filter when the engine isn't running, and burns it off through the unlet manifold at cruising speed.

It has no electrical connections and the valve works entirely by vacuum.
It was fitted on various engines from 1976 until the end of the run in 1993, including the earlier carburetted engines.
I can find no exhaustive list of why some engines got it and others didn't, but in principle any engine could have the EVAP system.

Interesting stuff - i've got more experience on the ones controlled by the ECU which let the excess vapour in (again during cruising) while easing the normal amount of fuel metered into the engine to maintain a good mixture control.
