I can't find it! It's not the same as on an early car, i.e. not here: JagRepair.com - Jaguar Repair Information Resource


Can someone provide a photo or describe where it is?

Thanks!

 

Tony, on the 2005 and up MYs, I believe that the Schrader valve had been replaced by the "fuel system pressure relief valve". Now I am not a Jaguar tech but from a little bit of research I have just done looking for the Schrader valve this is what I deducted. Again I am not 100% sure on this but I would bet that my assumption is correct.


In the picture below is what alldatadiy is calling the "fuel system pressure relief valve", I say that this is a replacement to the Schrader valve because there is a "special tool" gauge to read the fuel pressure, a bit different from the "usual" Schrader valve gauge. You will have to remove the cold air intake tube from the TB to the air box to access.


With a bit of luck maybe a Jaguar Tech will chime in.

 

Thank you, Rick. I did remove the intake tube and I did see that thing, I even tried to remove the part sticking out the bottom, thinking it was a different type of valve where I could attach the gauge (the gauge I am using has about half a dozen fittings), but I couldn't figure out how to open/remove it! At least it looks like I am barking up the correct tree!

Hopefully a Jag tech will chime in . . . if not, the weather is going to start to warm up in a week or so here, and I may just pull the wheel arch liner and test it at the fuel filter!

Thanks,

Tony

 

Ok, I talked with Bob "motorcarman" last night via PMs. Bob mentioned that car manufacturers are going with more and more computerized readings thru the communication ports. He mentioned about the "special tool" pictured above that is more for us DIYers rather than the professional techs.


Hope this helps.
