Fuel system XJ6C 1975
Hello you guys.
I own a Jaguar XJ6C 1975 under renovation I'm working now on the fuel system. There is a unit that is mounted under the front right wing of the car. It connects to the fuel system for carburettors. What is the role of this unit and whether it is necessary in a warm country like mine (Israel). I would appreciate an answer https://cimg1.ibsrv.net/gimg/www.jag...4cf992508c.jpg https://cimg3.ibsrv.net/gimg/www.jag...262ee2f3f2.jpg |
Thats the vapor canister. It stores fuel vapors that gas off from the cars fuel system when it's parked. They get absorbed and stored by the canister which is filled with charcoal aggregate. When the engine is started and running it draws in a slight amount of air flow through the canister to purge the vapors. This type of system is probably more necessary in a warm climate where fuel is more likely to vaporize at higher temperatures.

Thanks for the explanation.
How do I know if this tank is normal? And how do I connect it, I mean what connection goes to which pipe? |

P- should read" Purge- goes to manifold source |
also known as Charcoal Canister. it collects fuel vapors from the tanks, then passes the vapor to the engine intake through pressure check valves to be burned in the combustion.
if it did not have liquid fuel inside it when removed, it is probably good. |
Thanks for the explanations,
I'm going to assemble the entire system now. |
I've considered this as a part of the emision control system In olden days, tanks vented to the atmosphere. this device directs the fumes to the engine via the cannister.
Very similar to the GM product in my parts shed. It in turn very similar to the "Jagguar" unit in my newer Jaguar. Closaed vent vs open vent for the fuel tanks… Carl |
Is there any issue with removing this charcoal canister? I changed my car to triple SU's and removed all of the emissions equipment. My canister was full of oil and dripping on my RF brakes. Charcoal was non-existent. My vent hoses from the tanks are simply venting where the canister used to be. Hasn't seen any above 70 F degree days yet...

maybe not. My carburetted 1965 S type has none of that stuff and it is a twin tank Jaguar too. The gas caps in the S type say "non vented".
but about what was designed 10 years later, I don't know. The way you have it right now is considered "venting to atmosphere", or open. |
