Fuel filter location

Thats the active charcoal canister, it store fuel vapour from the fuel tank & the other pioe goes to the inlet manifold so it can vent the fuel vapour back into the engine.

Does anyone have an idea what this is?

[MattBLancs]

Not certain, but I'd think that likely to be the charcoal filter - allowing the fuel tank to vent, when the engine is not running (fumes directed to inlet manifold when running) and the charcoal absorbs the petrol fumes.

I think Wheeler gave you your answer

Picasso Fan, stop worrying about the filter.
Citroen/Peugeot stopped fitting service replaceable petrol fuel filters about 20 years ago.
Your car does NOT have one.

As already mentioned, they are only fitted to cars delivered to markets deemed a "dusty atmosphere". For example, my 2011 DS3 has an inline fuel filter. I'm in Australia.

Having said that, I would have assumed that South Africa would also be one of those markets. Perhaps it is not.

For reference, here is a pic of my DS3's setup. The large round cylinder is the charcoal canister and the small round one is obviously the fuel filter. This is located between the exhaust pipe and the right hand side of the car.

AFAIK, when PSA went to the fancy rectangular charcoal canister (like you posted) the inline fuel filter was also deleted.

My 208 and my 308 do not have an inline fuel filter (despite still being in Australia).

My NZ market 308 does not have a petrol filter. I presume that it is not intended to be driven in rural areas with gravel roads...

Unless you are driving around with the fuel filler cap removed, then I would have thought the road surface should not contaminate the petrol and require a fuel filter. A filter might only be needed if the fuel supplier does not provide good quality fuel or the car petrol tank is made from steel that can rust as in decades old cars.

Great, thanks for all the answers.

Reason for me suspecting the fuel filter, is that my vehicle has a slight misfire under 2500rpm but once pass that, it runs smooth. On the open road, it runs perfectly, but through the gears, it stutters. Logic tells me that if it is the fuel filter (non existent), it would starve at high revs. I am looking to change the CPS (crankshaft positioning sensor).
