Seeping Fuel Tank

On a fill up today I noticed wetness and a petrol smell from the tank, the rust hole is situated above the seam ( so it only leaks when tank is more than half full ) adjacent to the diff.
1. Is there a quick proprietory sealant/cement for
this type of leak?
2. ........and will the repair satisfy an eagle-eyed MOT
tester ?

Quick Steel or Plastic Padding Leak Fix are both good 
But for a real good permanent seal, have a look at this company....
.......http://www.devcon.com
I used their steel putty to repair the t-stat housing on my MK1 Granny about 8 years ago & it's still solid

I agree. These steel paddings are excellent.
Obviously this is one job where you remove any crud, before you do the repair, with hand tools and NOT with a power tool where sparks could prove interesting!!

£45.50 sounds VERY good, but if it's only a very small seepage, then padding would still make a lasting and effective repair. I'd only buy a new tank if it was a terminal leak myself. A lot of hassle changing the gauge sensor, filler, electrics, might uncover more problems than at first anticipated.
These modern adhesives and sealants etc are really very very good. Really depends how small the leak is, and where it is.

SD, I agree but if the tank is rusting through in one place then it won't be long before it springs a leak in another

If it really is an isolated rust pin hole and is in a flat part of the tank, then you could try the self tapper solution. Screw a large, course threaded, self tapper with a large pan type head into the pin hole, with a soft washer to provide the seal.

Thanks chaps, while the price of a new tank is surprisingly cheap ( for Ford that is ) the hassle of fitting it is far too much bother.
As it's ( hopefully ) an isolated rust bubble, a quick splodge of sealant should do the trick .

Not much hassle involved, two bolts holding the straps on and a couple of screws at the filler neck.
The pipes/wires all connect through the top of the tank and come off in one piece unscrewed from above

I got a replacement tank from Buypartsby last year. It was fairly easy to fit although the original strap bolts were too short and I had to find some longer ones. The only real problem is what to do with the old tank. The Household Waste outfit don't like old petrol tanks.

I have had excellent results from the two part putty stuff halfords sell, used it many times and never had it fail.
Apparrently it can even be sanded and painted (may help at mot time)

The leak's getting worse now, I made the mistake of parking the car facing down a hill with resultant pointing and tut-tutting from passers-by as valuable petrol from the tank piddled down the street.
If Highlander can furnish me with the address ( I've forgotten it already ) of his Broxburn Stately Home, I'd like to pay him a visit for a replacement tank.

hmmm looks terminal now me thinks!!
picture the scene...... innocent member of the public strolling along having a fag, then chucks the fag end on the floor just behind this car with a slightly leaky fuel tank...........BOOM !!!
and for £45 new, this danger could have been avoided rather than debated. All I can think is the kid who owns this has money to burn, petrol costs 85p or so a litre and his is spilling onto the highway or evaporating away !!
does this come down to lack of maintainance/servicing as mentioned in a previous thread. Scorpios ran on a shoe string.
tsk tsk

Aaaaaar Jim Lad. I agree. Tis a bad thing when the old chewing gum falls off, and leaves leaky things on the road.
I can only be 'umble M'Lud!! It's definitely the noo tank methinks!

Noo tank and a noo boot solenoid /motor thingy too , I can't get me boot lid closed now!
Had to drive home with a bit of flex holding the boot lid down and I will have to leave the car unlocked all night as the the alarm will activate if the boot isn't properly closed.
I'm thinking the Mondeo has the same solenoid fitted to its tailgate, should be easy to get one from a scrappy.

Boot lock now fixed ( the Mondeo actuator is exactly the same ) and through the kind generosity of that Top Man Highlander I now have a replacement fuel tank. 
Will endeavour to fit it when the weather is more clement.
