The fuel pump has failed on my 1999 XKR, I have read somewhere that it is possible to access it through the sub-woofer on the back parcelshelf, has anyone done this? Also is it possible to repair the pump or is a definate replacement. Also any pics etc. would be a great help. Many thanks.

 

Ok, the 4L XKR has two separate fuel pumps. Coupes can do the shelf route of access where convertibles you are either cutting an access panel in the body or doing the under car route. I've done the under car route and with the right tools, you can get the tank out of place to where you can reach in through the top in about 1.5-3 hours depending on your flexibility.

Replace both pumps, both filter socks AND replace both in tank leads (the wiring). They are so cheap and used in so many vehicles, the airtex brand pump PAIR is well under 100 USD with socks. The wires 7 years ago were like $150 for the pair.

You need to use a fuel line disconnect tool under car to get the fuel lines disconnected from the tank. I made a slotted piece of copper tubing that basically went around the fuel line and allowed me to really push on the little plastic disconnect tool. Then I had a rope around the line that I pulled on.

 

To my knowledge, the parcel access is only possible for the Coupe. The 4.0 XKR has 2 fuel pumps. Typically, the secondary is rarely used and dies silently. When the primary dies, then you are stranded. There is a switchover mechanism from primary to secondary when the car is started unsuccessfully a number of times (6 times?), so you can always try that in the off chance the secondary is still operational.

The 4.0 XKR fuel pumps are considered inexpensive enough (and hard to reach) that folks just seem to replace them with new parts. I believe there are after-market alternatives. I assume that if your pumps have been left to gum up in old gas, it might be possible to salvage them with an aggressive cleaning "on the bench", but I am not sure if the cost/benefit is worth it.

Best of luck, keep us posted.

 

Thanks guys, it is a coupe (I should have said). I will have a look for the new pumps. where is the second pump located?

 

both in the tank. Don’t buy the cheapest pumps you can find. Doing the same job twice is no fun.

PS. NOTE: cutting a hole in the parcel shelf is breaching the firewall protection. To be safe, & to have fire protection inside the passenger compartment one should repair the cut off portion in a fire proof manner, not just glue some fiberboard and carpet over the hole. At the minimum, some sheet metal should be riveted over the opening, and even that’s on the janky side.

I fully understand why the hole method is an attractive option for some owners, but I just have a different opinion about the procedure. No big deal, everyone has different ideas about everything, as the recent election illustrates.

However, for my money, I’d rather pay someone to R&R the tank than be cutting a hole in a firewall area. I know these cars are at the low end of the depreciation scale, but I still don’t like to do a repair in that fashion.

Yes iv gone through the sub to change the fuel pumps.
I would not reuse any old pumps, just get two new ones with filters.

Got mine from britparts, (after market direct replacement ones), this means no modifications needed to the holding rubbers or splicing link leads for different plugs will need to be done
I just reused the original link leads as there was no heat damage to the wire or plug, and i reused the evap seal.











Hope this helps...

 

Would this be the correct website?

Yes...............
There are others that sell this fuel pump but thats where i got mine from..

 

I have no experience with the one that BP is selling, however personally I would be very hesitant to buy a no name brand fuel pump, not just for the work to replace one again but if it starts underperforming at high flow it can be running lean, which could be risky. Some of these pumps can be louder as well.
I understand Jaguars original Denso are pretty expensive, though there are some known Brand names that also make these pumps, Bosch for instance, just do a search.

 

Given that the coupes came from the factory with a hole cut in the firewall for the subwoofer I really can't see its a big deal to cut a hole yourself to access the fuel pump. To ensure your work is as safe as the factory's you could always fill the hole with a subwoofer, or as others have done, rivet a metal plate over it.

 

I had three months ago the same problem, remember a XKR has two fuelpumps and it turned out that one of them was already at fault for more than two years or so so when the second broke down it came to a standstill.......my garage replaced both through fiddling with the fuel tank, in the luggage compartment. So they got enough space between the back seat and the fueltank in order to get the pumps in.......seems they got it done in less than a hour

 

I too encountered a similar experience on XKR Coupe and both pumps had failed. The removal can be done from access in the boot and as someone has said "as long as you can be flexible enough to contort your arms and body".

1. The sub woofer/cover is removed and enables you to gain moderate access from the rear seats and the top of the fuel tank where the pipes and connectors are located.
2. You can then reach in either through the 75mm gap in the boot or from the sub woofer space and remove the pipes wiring clips and cover plate by twisting the locking ring.
3. Using a wrench you can then remove the fixing bolts securing the pumps inside the tank....be careful not to drop anything inside the tank and use a magnetised socket for removing the fixing bolts.
4. The pumps are then able to be removed and replaced.
5. Installation is the reverse of the above.....
6. Total time depending on your flexibility is around 4 hours.

Upon inspecting the pumps and disassembling them, the plastics forming the armature inside the motor had melted, due to lack of cooling (fuel) in the tank...... Lesson learned dont let the Mrs use the car and nearly empty the tank too often,,,,,,,!!

 

I agree. I removed the tank rather than cut and repair when I replace my fuel pump. My biggest reason for taking that approach is that this was my first time doing this on my Jag and once the tank was out I could easily see what I was doing in there and had a better chance of doing a higher quality job inside the fuel tank. Then I put everything back together just like it was supposed to be and this is the result I wanted.

 

Agreed ^^^^^^^
I would rather the jaguar fuel pump, but with the xkr it becomes expensive...
The pumps i received from BP had uro stamped on them, i cant really give a recommendation as iv only covered about 5000 miles (about 2 year) since replacement and the original jaguar pumps gave up after 95000 miles..

What i can say is up to now, im very satisfied with the pumps iv fitted and the difference in performance is unbelievable.
.but i could have been running on one pump since buying the car (and i thought it was fast then)

I have read that some pumps dont fit correctly and need adapting.....

 

My fuel pumps have also packed up, mines a convertible, I don’t really want to cut holes, so I’m going to try and release the fuel pipes underneath, but a Jaguar specialist advised me not to go that route because the quick release attachments become corroded and could break and Jaguar don’t produce that part anymore, I’ve been firing WD40 into them for a while now, so I’m going to have a try over the Christmas period. I’ve looked at the aftermarket pumps.....I don’t know, I’ll probably go with Jaguar. Once you get past the fuel lines release it’s not a difficult job, just a bit fiddly. I’ve seen all the videos, I could almost do it my sleep now.

 

Iv just done a check on URO (the U in uro has two dots above it)
Manufactured by A.P.A industries inc. (simi valley CA...USA)

A.P.A's OEM division currently supplies products to Mercedes, Jaguar, Saab, Mitsubishi and is currently holding discussions with Porsche.

So if the above car manufactures are happy with A.P.A to let them supply some OEM parts for there cars im happy with my fuel pumps made by them.

Not saying A.P.A supply Jaguar with the fuel pumps they sell but they do supply Jaguar with some OEM parts.....

 

Good that you found at least the name of the manufacturer, I would already be a bit less concerned here, though would still have a slight bias towards Bosch for an aftermarket ;-). I am running totally different Bosch units on my car from 2010 or 2011 iirc and guess roughly 100Kmiles on them, but not a measure of course.

 

Okay.... Ive ordered the British parts fuel pumps, you convinced me XKR-DAY, or it might have been the £300 difference in price. Has anyone in England done the fuel lines?every time I hear someone’s managed to release the fuel pipes they live in a nice warm climate and the the underneath of there car looks nice and clean.

 

Take all the carpet out of of truck .get a siphon pump to drain gas tank. drain the gas out and let it sit with the tank door open to get all of most of the fume out. Pull the carpet out of back window well . if speaker is in window well remove it to see if u can see gas take .if not get a 8 in. Metal cutting Whole saw, find center of window well . put wet blanket over gas tank over top of tank from the trunk. Drill out the hole in the center of window well and you should be able to see the tank pullout on top of tank. take off the ring claps and pull up . This should let you open and take the hose adapter plate off and give a hole into the fuel tank. The fuel pump is to the right of this hole and is held in place by a clamp .take out the bolt on the right and loosen the one on the left .this should release the fuel pump, so you can take the fuel pick up hose off and take the fuel pump .Put in NEW fuel pump in reverse order and it will work ,I did mind that way and saved over$2000.00 the the Jag dealer wanted to replace the fuel pump .My cost less than $150.00 and about 4 hard working Hours .I have driven over 4000 mile since I did this . I have a 2000 XK8,

 

If it helps any I did this recently on my 97 (just one fuel pump but otherwise mostly the same I think).

I used a Denso fuel pump, a Jaguar fuel pump filter sock, a jaguar fuel filter, and some Viton o-rings from Harbor Freight for the fuel filter. Furl filter is under the car and vaguely near the left rear wheel. Be sure to change the fuel filter too. I think most fuel filters come with new o-rings but the OEM Jaguar one doesn’t which I did not realize. Using the Jag stuff was probably not necessary. The pump I took out was Denso and I believe that was the Jaguar OEM, so no wiring mods were needed.
