I don't know if it's a problem with my unit or is it really another one of the design problems that the 2008 xk has.
When refueling, when placing the hose I refuel very well, but at which the trigger of the pump jumps if I continue to fill very slowly, about 6 more liters of gasoline enter the tank until it is completely filled.
It really is a drawback having to refuel so slowly or leave the tank with 6 liters less than it really fits.
Is there a solution to fill it up quickly?

 

I have the same problem on my 2007.
The problem has been addressed before on this forum, I just haven’t done anything about it yet.
There’s a canister that the air is supposed to pass through to get out of the tank as the gas goes in.
Over filling the tank with gas will cause some to get into that canister and ruin it. Probably done by a previous owner. Got to replace it to fix the problem.

 

I can't understand you.
I am Spanish and the Google translator sometimes does not make a very good translation for me.
Do you mean to replace some element of the tank filling system?
If so, I would appreciate if you could explain what piece it is since I have tried to use the search engine in the forum and have not found anything.

 

evaporation system for the fuel tank

evaporation system is clogged causes air pressure to rise

Hope this helps?

 

Interesting topic.
I'll look to find out if that's the problem.
thanks

 

Yes, Cee Jay pointed you to the problem. The filler neck is short and you are putting the nozzle in too far, past the evaporator line. When you put gas in the tank, air must escape. It escapes through the evaporator tube but your blocking the evaporator tube because the nozzle is too far in. Try only putting the nozzle in 1/3 of the way when you fill up.

Also, when the gas pump stops, don't keep clicking the nozzle to top off the tank. If you do, as KJ07xk explains, the gas goes down into the evaporator canister and destroys it eventually.

More specifically:The main purpose of the Fuel Level Vent Valve (FLVV) is to control the fill volume of the tank. During filling, vapor is passed via the FLVV to the Liquid Vapor Separator (LVS). The vapor then passes from the LVS to the vent connection via a corrugated tube. The vent connection is connected to the charcoal canister which stores the fuel vapor. During filling, when the tank reaches its full level, the FLVV closes and prevents fuel vapor passing through to the LVS. This causes the pressure in the tank to rise which in turn causes the pump filling nozzle to turn off.

 

I have had this problem in the past on my 2010 XKR but only at specific gas stations whose pumps are set at too sensitive for the automatic shut off. I never have the problem at my local Shell Gas Station but always have the problem at the USA Oil station near my office. Sometimes, if I turn the nozzle upside down with the handle facing upwards I can get it to work.

 

I have had the problem a few times. Each time I have had the problem, it turns out to be a pump problem not a problem with my car.

 

I’ve had the problem at every pump I’ve tried, various brands, local and out of state.
No doubt, my plumbing is constipated.
