Jaguar World Monthly Forum - X308 fuel pump issues

My car needs secondary pump and both pumps will be changed next week, but most probably using a bit more traditonal way to do it

 

I've been thinking about this approach for quite a while ....I have an air operated 'nibbler' to open the back parcel shelf metal.
Sure beats the hell out grubbing around underneath getting a face full of petrol/gas and trying to undo those damn pipes ;o))

 

I am doing the exact thing on my xj8. Pump died after 6 months and my subwoofer is toast. Cost me 300 bucks after being stranded an hour away yesterday.

 

What pump are u going with?

 

2xWalbro 255. I think for your XJ8 best choice is OEM pump. There are too many cheap "ebay pumps" on the market.

 

So u would go with the denso?

 

There is nothing wrong with this approach. I've seen it done. If Coventry didn't design this car to maximize the profits on the "back end", there would be a "trap door" there, to ease the fuel pump replacement. There is nothing wrong in putting a "custom trap door" in that place. No structural changes, and once the shelf is back in place, nobody is any wiser.
I highly recommend this method.

 

It's what ima do!!

 

I agree...stay with the OEM pumps.
You may pay a little extra but it's worth it.

 

It may look a bit crude but it sure eases the stress of climbing around underneath....gettin' too old for that caper ;o]

You gotta remeber that Jaguar is not alone in this regard...most manufacturers follow the same route these days.
That tank is installed first while the car is swinging at head height, the assembly worker just reaches in and hooks up the tubes, then the driveline is 'married' to the chassis as an entire sub assemmbly....mere plebs like us don't enter the equation ;o]

 

If that is done where I live and some-one in authority was to see it the car is a structural write-off. The parcel shelf is considered here to be an integral support panel.They often check to see if extra speakers have been fitted and if there have been holes cut then it has to be repaired and an engineers report done.(very expensive and no guarantee it will pass)

 

Engineers report? Really? Jeeze!

Once you put it all back together, (properly) there is no way to tell that the work was done. The parcel shelf cover hides the work. So, unless you open your mouth..........or your neighbor rats you out to the Department of Parcel Shelf Alteration Department, (Vague Monty Python reference there, lol!) you will probably be OK.

You guys in Oz have a tough "Nanny State" there don't you?

Wow!

I've been to your beautiful country few times, but I never lived there, so I was never exposed to any bureaucracy. But this is nuts! And I thought "they" are taking our freedoms away from us, over here (which they are!).

Just goes to show you that the terms "country", and "government" are not one and the same (despite the government trying to convince you otherwise).

Too much is too much. They all need to be voted out, and some normal people put in. The problem,......normal people don't run for political offices.

 

We did ours and damn it's great way to replace a fuel pump. My hose came loose so it was fixed in a few min.

 

Hahaha....Gippsland lives in the 'Nanny State'....it's called Victoria! ;o)=)
Now, little ol' me lives in the 'Swingin' State' Tasmania....just swingin' below Victoria and we don't have any such troubles.
If the job is done properly and panel is placed back in postion or a larger panel piece fabricated to fit which can be screwd back in place, there is no problem and no comprimising of veeehickle integrity ;o)

 

We are known here as the Nanny State. It gets worse!
Buy a used car and want it Road Registered. 1st you MUST get a "Certificate" from a certified mechanic.
Easy? No, all wheels are removed and brakes,suspension,ball joints,any leaks,window tint,seat belts,any rust,alterations of any sort (parcel shelves are known to have aftermarket speakers) no marks on the windscreen,exhaust,everything is inspected,any defects are photographed and held on file. You have 7 days to present it with defects fixed.VIN and Engine numbers are referenced via computer data base. It is rare for a car to pass on first attempt.
My Jag with such a certificate from another state (other states certificates are not recognised here) failed all brakes,rear mufflers,ball joints,headling (slight bubbles) rear bushes,windscreen,mis matched tires (tyres,here) and other minor faults. You could take a new car to these guys and it would fail!

 

Just a note to those replacing these fuel pumps. The manual says to siphon the gas before removing the tank - no sure how this is done since there is a screen/cap at the bottom of the fill pipe inside the tank - well above the bottom of the tank, there's no clearance above the access flange and the vent lines are too small. I had the pleasant experience of removing the fuel lines from a 3/4 full tank - with only the loss of an ounce or two of gas. On the supply line the pump prevented any fuel flow out of the tank and on the return line there is a simple one way flap check valve that prevents gas from flowing out of the tank. I had the rear suspension carrier out so access to the pipe connections was not a problem. Just wanted to share my experience.
