2014/XKR X150/19,000km/5ltr. While filling fuel, petrol pump cuts out when ever the flow is above a very low flow rate which leads to an extremely slow and tedious refueling process. This must be a problem experienced by other XKR X150 owners.
I would appreciate any assistance and suggestions.

 

This problem has been discussed many times and I have experienced it with my 2012 XF and also my 2015 XF which was bought new.

For my problem with my 2015 car, the solution was found by replacing the fuel filler neck with a modified version that Jaguar had put out. This was done at a Jaguar dealership and while the car was still under warranty. It took the dealer about an hour and a half to change my filler neck to the revised one and I have not had a problem with filling up the car with gas since this was done. The work was done about 1 1/2 years ago and the problem has not surfaced again since the new designed fuel filler neck was installed..I wonder if there is a revised and new designed fuel filler neck for your model which may very well correct your problem.

I would discuss this with dealer. Good luck.

While it MAY be a filler neck problem, most slow-fills are caused by the Vapor Cannister, or "Evap" cannister. The carbon filled container hooked to the vent tube of the fuel tank. It clogs and prevents air from escaping during a fill, which over-pressures the tank and causes the pump valve to trip off.

 

 

Hello Graham,
Thank you for your assistance, I am still feeling my way into Jaguar Forums.
I have had some extremely helpful replies already.
I am so pleased I have joined with Jaguar Forums.

Also to add from what I've read, it's a side effect of overfilling the tank. Fuel gets up in the canister and turns the media into mush. I've needed to train myself into just going to the next 25 cents when filling after it clicks off the first time.

 

Not if your vehicle is European specification - only USA, Canada and Mexico specifications have the filler pipe with "Evap". Here is the filler pipe on my 2014:



It's a plain pipe and the only restriction is the splashback flap (this photo was taken as I replaced the filler bowl):



I've never had a fill problem with either my 2007 or 2014 XK's and I've driven them across England, France and Spain so have used a lot of different service stations.

However, there was a problem a few years back with Jaguars at many UK service stations. The fuel delivery rate was too high, fuel couldn't pass through to the tank quickly enough and soon built up in the filler tube until it triggered the pump cut off. The solution at the time was not to squeeze the pump trigger fully open and rotate the delivery nozzle through 90 degrees.

Two things appear to have happened here - trigger locks are no longer fitted (so you can't put the pump on then walk away and leave it filling - have to hold the trigger on) and flow rates have been reduced. I think this was most likely done because the money dial was rotating so fast it became a blur! It costs 85 UKP / 111 USD / 150 AUD to fill my XK.

Since I don't know, I will ask;
If Euro-spec cars don't have an Evap on the tank vent, there then should be a vent WITHOUT an evap canister. The air that is already INSIDE the tank needs to be dissipated whenever the tank is filled, and the filler neck is full of liquid when being filled, so then WHERE does the displaced air go????????
I really don't think that European spec tanks would have a direct-to-atmosphere vent line, that'd be dangerous.
Whichever, wherever, however, there needs to be a vent on the tank. That's where the problem may lie.

 

Of course, I never said the Evap was on the Filler Neck.....
I did a search, but of course I only have the North America WM... US doesn't have it on the filler neck either.

 

YES - there has to be a vent but I haven't got a photo which shows anything relevant. My main concern at the time was replacing the filler bowl.

Here's a comparison of the two fillers from JEPC. European pattern on the left and USA pattern on the right:



The fuel tank parts listing has a number of vent pipes so that could be the route.

Thank you for your information. I am booked in to the Jaguar dealer next week.
