Hello Folks,

My car went into "reduced performance" mode the other day. the code reader was 0P0087 - Fuel pressure system / system pressure. Error
The breakdown guy suspected fuel filter
After some investigations it turns out the after VIN 32753 models (mines a 2010 40000 something) don't have a remove filter

Can anyone confirm this as true?
I did a search but just lots of people changing the filter itself which is confusing.

So if that is the case, where if the filter? the garage said that jaguar told them the filter is integral to the pump unit ad is for "life"
I'm an engineer and the term "life" really annoys me, life for jaguar is either defined as 3 or 6 years up to 60k miles, at which point they want you to buy a new one
My vehicle has 100k miles and 12 years old, I'd like to actually change the integral fuel filter.

 

The only filter the 5.0 cars have is the sock on the pickup inside the fuel tank. So, not really a 'filter' per se.

Cee Jay, So what is the filter situation on a '09 XKR?

 

I would suspect that a failing pump might be more likely than a blocked filter so you will probably be changing the fuel pump anyway but I would definitely check all the electrical connections first. The garage should be able to check the fuel pressure to be sure that it is really the source of the problem. I don't know about the X150 but the fuel pump itself was certainly a weak point with the X100.

'09 4.2, or '09 5.0?
4.2 has an in-line filter. GGG probably has a really nice picture of that also, cuz I don't have a 4.2 WSM, just the 5.0 one.

 

Might as well have details of both 4.2 and 5.0 in the same thread:

Easy to replace from under the car. In front of left rear suspension. New filter was about $20 when I replaced mine last Fall.

 

I would have thought that the pump is more likely but it could be the pressure sensor:

I had the same thing happen with the Disco last year, same parts as yours. Replaced the rail sensor as that was easy and cheap. New sensor didn't fix the problem so replaced the pump in the tank and problem resolved.

 

My experience with the naturally aspirated 5.0L fuel filter:
Note the cup-like structure shown at the bottom of the flange.
Probably the same part as an XF, although on-line catalog says not.
Verify part numbers as they may be superseded.




The tank flange has an integral filter.

 

Thanks for all the detailed responses guys. really clears it up

Is it a common modification to add a fuel filter?

 

Never heard of anyone doing it as the factory filter’s sufficient, as the last poster said the filter’s built into the removable flange on top of the fuel tank. Here’s a pic of the OEM filter.

 

erm, this was my original question does it have one of these?
person above says only a sock

 

It is indeed a fuel filter, integrated into the fuel tank flange. It’s a serviceable part and has been the subject of multiple recalls over the years for cracking and leaking fuel. The flange/filter connects directly to the in tank LP fuel pump which sits on the bottom of the tank. The fuel pickup has a plastic mesh “sock” which protects the pump from larger particles and the fuel filter further cleans the fuel prior to the fuel lines, injectors, etc.

 

V7SPORT; Thanks much for the info. Just ordered part.

My 5.0 XK flange cracked open and leaked nasty yellow stuff from the filter inside the flange.

The reason for cracking most likely is due to high pressure and clogging of the 60 micron filter as well as age of hte plastic.

The flange can be accessed by removing the rear seat (it lifts up) and underneath a rubber grommet, however the bolts
are very hard to get to and may require lowering the fuel tank slightly.

 

This finally makes sense! You learn something everyday ....
But it is a really expensive way to change a cheap filter

 

"filter".
More like an old gym sock.
