[xj] Re: [xj Leaking fuel tank

Max,

Please use the good tank while you remove the leaking tank and let it air out for a bit. A
good reason not to just keep driving on one tank is what do you do if the other tank springs
a leak. Get both of them working well and enjoy the car.

After you let it air out for a while, are there any radiator or other tank type shops in your
area? You could find a like new used version here in the states and ship it to Oz for that
kind of money, so what they are proposing will make them very happy by paying the rent for
the month.

Hopefully some other Jag people from Oz will chime in and give you some parts sources
but $1000 AU is a bit much unless the tank is lined with gold.

Try looking here: http://tiny.cc/OgN9z $400 USD and you could ship to Australia and still
be almost half price of what the dealer is trying to charge. I would look around where you
live for a better deal. Starting with a normal mechanic and not the dealer.

Hi Everyone,

The fuel leak out of the left hand tank of my 1983 XJ6 Vanden Plas
has now become so significant is is a potential hazard.

My dealer has suggested removal and reconditioning at a total of
around $1000 Australian Dollars.

Am finally wondering if the money I spend on this car is reaching a
point of negative return, so was therefore wanting to ask if anyone
knows if it is possible simply to drain the tank, leave it be and
in future run the car solely on the right hand tank?

Any suggestions would be greatly appreciated.

Kind regards,

Max Renouf

In reply to a message from joe@joea.com sent Wed 30 Apr 2008:

Joe,

Good suggestion on the tank…
One thing to note about the tank on the link you provided is that
it looks like their replacement is bare steel.
The past week as been another one of those weeks where I send alot
of time getting tanks out of some of my parts cars. I’ve had a few
of those bare steel tanks (one in a 72, another in an 87) that
didn’t fare too well. The OEM tanks (painted and sealed) normally
look alot better coming out of the car.
There are reconditioned tanks out there for about the same money,
that have been alreay sealed and primed. MotorcarsLtd sells them,
and another company (tank renew or some such) that does the same
thing.
Another possiblity is pulling the tank, and doing the sealing
process himself. If there are no raidator shops nearby that can
clean it, a Muratic Acid bath will normally do the trick. Then a
tank sealing kit, which has the cleaner, rust encapsulator, and
sealer can be purchased from POR15 or Eastwoods for around $75 USD.
Check out this link: (VW link, but good general information)
http://www.ratwell.com/technical/FuelTankRestoration.html

Zurdo’s advice about making certain the source of the leak is a
good one as well. There are two lower hoses that could be the
culprit, as well as the seal around the plug.

Good used replacement tanks are also available for $50 from some US
used parts suppliers. Should be close to the same $$ in Oz.

Finally, it is possible to isolate the tank. But not only block off
the return fuel, but also the changeover valve in the boot. If fuel
gets throught the valve, it can cause fuel going into the bad tank
as well.
Since it’s the left tank, and the fuel defaults to/from the left
tank (no voltage at the valves), you need to also consider
bypassing the valves with solid pipe. Otherwise, if any of the
valves stop opening properly with voltage applied, the return fuel
has nowhere to go.

Good luck with it
