Hello guys. Have any of you ever disassembled the canister?
I understand that it is on top of the gas tank and I think I will have to disassemble it to check or replace it since every time I go to refuel it is impossible to do it quickly since the gas station pump does not stop jumping.

 

"Canister" - fuel filler bowl (item 1) or fuel filler pipe (item 3)....?




Graham

 

or the emissions vapour canister??

 

I mean to disassemble the carbon canister of emissions

 

I've never had any trouble with this so it didn't enter my head when I asked the question.

I've added "carbon" to your thread title for the benefit of any others as stupid as me.

Checking the specifications for the 4.2, I see the US and European build evaporative emissions have several different components. I don't think this affects your basic question about disassembly as the canisters only appear to have different capacities and type of carbon content but it could make a difference when considering how the vapours vent during refuelling.

Your location reminds me of parking my Jaguar at the Old Port in Barcelona. Happier days driving across Europe - let's hope they soon return.

[QUOTE = GGG; 2349234] Nunca he tenido problemas con esto, así que no se me pasó por la cabeza cuando hice la pregunta. : icon_doh:

He añadido "carbono" al título de tu hilo para beneficio de otros tan estúpidos como yo.

Verificando las especificaciones para el 4.2, veo que las emisiones evaporativas de la construcción de EE. UU. Y Europa tienen varios componentes diferentes. No creo que esto afecte su pregunta básica sobre el desmontaje, ya que los botes solo parecen tener diferentes capacidades y tipos de contenido de carbono, pero podría marcar la diferencia al considerar cómo se ventilan los vapores durante el reabastecimiento de combustible.

Tu ubicación me recuerda a aparcar mi Jaguar en el Puerto Viejo de Barcelona. Días más felices conduciendo por Europa, esperemos que regresen pronto.

All the comments that I make I translate them with Google and sometimes I put the words as they are said in Spanish and it is translated in an inappropriate way.
I have read that when it costs a lot to fill the gas tank it can be the cause of the carbon container.
I have put a plastic guide through the aeration tube and at about 60 cm it is blocked. I assume that the carbon container is clogged and does not let the tank breathe and hence my filling problem.
That is why I would like to be able to disassemble it to be able to try to undo or replace it.
Greetings.

 

I'm also looking forward to the day that we can move freely everywhere again.

 

Attached is the Evaporative Emissions section for the Normally Aspirated engine from the Worksop Manual. The drawing and parts list may be useful.

The main differences between the US and European installations are the carbon canister size and the fuel filler pipe design and vent. The US also has a DMTL pump filter which is NOT fitted to European specification vehicles.

I have found service station fuel pumps in both France and Spain have a faster delivery rate than ours in the UK. This often trips the pump unless I don't fully pull the trigger to reduce the flow. Never a problem with our slower rate pumps here.

Pulled in behind this XK Convertible owner on the road between Madrid and Granada. It was the only other Jaguar I saw in three weeks.




That was my last 2007 XK Coupe.

Mine is identical to yours ... it is from 2008 it is also blue and I have the same 19 "wheels

 

but I was under the impression that the canister cannot clog as vapours are converted to fluid and placed back in the tank. Am I wrong?

 

[QUOTE = guy; 2350218] pero tenía la impresión de que el recipiente no se puede obstruir ya que los vapores se convierten en líquido y se vuelven a colocar en el tanque. ¿Me equivoco? [/ QUOTE]It is very possible that it is so, but I don't know.
If it were really like that, pouring gasoline through the small aeration tube that connects with the metal filler tube, you would have to clean the carbon and unclog it.
If there is someone who can confirm that it is so, I will be very grateful and will perform the operation to unleash it.
Greetings.

 

The PDF I added in post #8 should answer your questions on the components and operation of the Evaporative Emissions control.

Graham

 

You're right Graham, but I'm not sure.
If I put gasoline through the aeration tube, I see that it will go to the carbon deposit and technically gasoline is a solvent with which I should eliminate any possible jam.
But I would not like to spoil something else.
Do you think that if I put gasoline there I will solve the problem without breaking anything?

 

The canister is likely to be nothing more complex than a box full of activated charcoal. However, it is intended to absorb fuel vapour and soaking this in liquid fuel could destroy the charcoal. If there is a blockage, it must be in the atmospheric vent hose, the purge hose or the tank vent hose. As you have a re-fuelling problem, the atmospheric vent hose is the most likely culprit.

Can you get to the hose connections to disconnect and blow through them to check for blockage?

Graham

 

At first what I did was insert a plastic guide through the small breathing tube of the filler neck and notice that it removed an obstruction.
I do not know if I will be able to have access to disconnect the remaining hoses to check if there is any more obstructed, hence my question of if someone knew how to disassemble the carbon container.
I would not like to have to disassemble the entire tank to be able to access it, much less have to disassemble part of the rear axle as it would be a crazy job.

 

This is the Filler Bowl drain tube which vents below the vehicle:




Is the Canister vent (arrowed in red) accessible from the top of the Filler Pipe? It's normally hidden behind the Filler Bowl.








If not, the lower end (arrowed in blue) should be accessible to check for blockage.

NOTE: this is the European specification Filler Tube. The US specification has a different vent arrangement.

Graham

 

Right. I disconnected the tube in the area of ​​the red arrow and inserted the plastic guide to unblock it. When I have a while I will look at the end of the blue arrow if it can be removed to ensure that there is no traffic jam and if possible I will do the same with the rest of the coal access pipes.
Thanks for your kindness.
Greetings.

 

I have been looking at the vent tube that reaches the filler neck and it is totally clear.
Lowering the tank with the carbon deposit is very complicated because you have to disassemble the transmission, the rear silencer and surely the entire rear suspension.
Tomorrow I will go back to see if I can access the ventilation tube of the tank that connects with the carbon to be able to see if it is clogged.
It would be helpful to be able to remove the carbon tank without having to remove the gas tank, but I don't know how to do it.
Any ideas?

 

Today I looked at the carbon container again to be able to access the aeration pipes. It seems that it could be separated from the gas tank to be able to lower it and to be able to disconnect the tubes and connectors that reach it, but I do not know how to disassemble it nor do I know if the tubes and electrical cables will be long enough to be able to lower it and disconnect it easily. Does anyone know how to disassemble it?

 

It will probably take a saw. Seriously. Most canisters are glued plastic. You can cut it apart, do whatever needs to be done, and reglue it with the correct adhesive.
