Gasoline stong fuel odor ? - RESOLVED
Hello, 2007 xk, five days ago started smelling strong fuel smell in closed garage, with car not running . Can not find a leak. Removed engine intake cover, started engine, fuel rail and tubing all dry, no seepage after shutdown. Fuel filter just fwd of LR wheel, all dry and tubing dry. No performance issues. Can not find smell any where around car. Never smell anything outside or when driving. However every time car is in garage smell comes back ? any suggestions ??

My $0.02: I had a bad gas cap (replaced under warranty) that triggered a CEL, but no smell in my garage. The emissions system is a closed loop, so I suspect that other leaks in that system would also trigger a CEL.
Since gasoline is highly volatile and evaporates quickly, leaks may be hard to spot unless the fuel contains a conspicuous dye. In addition, if you have a pinhole leak fuel loss may only occur only when the fuel pump is running and the line is under pressure. I'd check the lines at the fuel pump and around the fuel intake (injectors).
In 2009, my Lexus 2007 LS460 was recalled because the aluminum fuel rails could corrode from the inside out from using certain ethanol fuels with low water content, which could cause a pinhole that could spray raw gasoline onto a hot engine and cause a fire. Those aluminum fuel rails were replaced with stainless steel rails. Fortunately, my car never developed a fuel leak. I wanted to point this out because I don't know if Jaguar fuel lines are aluminum or stainless steel.
If you can't find the leak and fix it yourself, since you're in Alpharetta I'm sure that Nalley Jag can help. I've been very pleased with their service and highly recommend them.
Good luck!

Thanks for info , I have visually checked all you mentioned , the gas cap would be a inexpensive try ! All data mechanical sight in trouble shooting chart suggest replacing the electric purge valve . It will arrive we'd . If that does not do it , it's off to Nalley Jaguar for extended stay ! Thanks !

Thread resurrection, only to add data to the search for "Fuel Odors".
This odor started on my XK about two weeks ago. I tracked it down to a bad fuel pressure dampener (basically an accumulator to dampen injector pulses in the fuel rails.) Was weeping fuel as the car ran.
A basic part, one on each rail, and snaps onto into place....
Problem: Jaguar does not sell what should be a simple $100 part.... They sell you the $1000 fuel rail instead... Grrrr
Thanks Jaguar...
Needless to say.... not buying it....
Benefits of a pulse dampener have been questioned for years, as they are known to cause of engine fires when they fail.
I will pull the unit hoping the mounting seal is what failed. Might be saveable...
If the diaphragm is gone, then I may thread and seal the opening, or adapt a dampener from another car.... (Probably $50 from Ford)
... Unless of course anyone has a spare dampener laying around?
Wanted to get this out there as it is bound to start happen to others as our cars age....

Call Injector Cleaning & Flow Testing Service - Injector Rx. It has been reported that they will cap the dampener for about $100 and several reports in the XK8 group of no adverse effects at all from a capped dampener.
I see older Jags use to put the dampener in-line with the cross tube between rails. Might be worth a look as well... Worst case , I'll tap and seal it myself.
BTW: RC Engineering is another recommended injector service here on the west coast for those interested.

Same problem Same model
2007 xk convertible 70,000 miles. Strong gas odor in cockpit upon start up. Disappeared when driven. Dealer replaced fuel rail. Odor gone. So is my money. Also had to replace faulty thermostat at same time. Someone once said owning a Jaguar is like keeping a mistress. Beautiful but expensive.
