Just make sure you still have a good metal to metal contact from tank to body shell so that the gauge still works.... :wink:
Thanks Berni.
I could always run an earth wire if needs must.

So long as you ensure at least 1 bolt has a clean 'thread to thread' contact and bare metal under the bolt head to the body, you should be fine.

Hi jagnut. I use glazing mastic which comes in a roll it's about 3/4," wide and 1/8 " thick good for bedding the gearbox cover as well available from any glass merchants

That is interesting and Byron Glass is very near me.
Probably less messy than a tube of mastic too.
I shall enquire.
Many thanks,
Mike.

Hi,
As an update, the original petrol tank is now out.
I am pleased to say it came out really easily, I simply gave the screws a soak in Plusgas first and had no issues as a result.
The aperture in which it sits is sound and solid, so no welded repairs are needed to the boot floor! :D :D
It even still had the old gasket attached and paint underneath. :D
I'm just hoping now that I can maneuver the replacement (larger capacity) tank in as easily as I managed to get the old smaller one out..........

As an aside, apart from being small, the original petrol tank is in good order.
There was even very little crud in the bottom of it when I drained the fuel out prior to removal.
So it will go on my 'Free to whoever needs it' pile of spares at the national.
I shall label it up as an original early series 2 tank of 5.5 litre capacity, I believe that is correct but feel free to correct me.
(Fingers crossed we're allowed to have a national this year......)
Best wishes,
Mike.

Sorry, I meant 5.5 gallons, as the original 803 engined series 2 petrol tank capacity.

You're right John, 5.5 litres wouldn't get you very far at all, even with an asthmatic 803 fittedl! :wink: :lol:

Hi,
I'm not sure that Byron Glass is currently open for business, so I have bought this online:

https://www.ebay.co.uk/itm/HIGH-PERFORM ... 2749.l2649
It looks like it will do the job and is even grey in colour, so will match the car.
Best wishes,
Mike.

Mike, how did you get on with this mastic tape? I’m ready to carry out a petrol tank replacement too. Just got the fuel pipe to disconnect now and it’s good to come out.

I was pondering the same sealant question. Must admit, never have metal to metal contact a thought...glad someone highlighted that.

Hi John,
I've refurbished the boot now and it is ready for the new tank but I won't be refitting it just yet.
However the roll of mastic has arrived and it looks like it will do the job well, when the time comes to refit the tank.
Best wishes,
Mike.

Hi,
Well I am now fitting my replacement (larger capacity) fuel tank into Sally my Series 2. Everything was ready (so I thought.....), so I applied the mastic tape around the outer edge of the aperture.....

So far so good, the mastic tape joins to itself together well, so no need to worry about gaps. It is also very sticky and stretchy...........
As I found out when I tried to sit the tank in place, it stuck to the tank as I **tried** to insert it into its aperture, wouldn't come off easily and stretched all out of shape, so much so that I had to remove it and start again.
This time with the mastic in place under the lip on the tank itself, a much better idea, one I should have realised was a better method of approach allot sooner..... Doh! :roll:

Now I've done this and with the properties I mentioned above, I am happy the sealant (correctly positioned :roll: :wink: ) will do its job well.
Earlier I used the word **tried**, I wonder how many realised where I might be going with that one............
You guessed it, the new tank didn't want to go into the hole the orignal tank came out of. I could see that 'persuasion' would be futile, so broke out the grinder and flap discs, took some metal off each corner. Now it slips in and out easily.
Just a little repainting then and it will be time to see if the screw holes line up..........
To be continued......
Best wishes,
Mike.

Hi,
The screw holes lined up fine, however the thickness of the sealant meant that the old screws were no longer long enough (they were rusty anyway), so I purchased some longer self tappers and screwed the new tank down. They look way too long now it's all tightened up but I see no point in unscrewing them and then having to source some shorter ones, it's not like they're in the way of anything under there.
NB: I haven't screwed one screw fully home, as it is used to fix the small retaining clip for the wire to the sender, I simply screwed it halfway for now, to locate it in it's hole and so I could give it and the clip a blast of Clarendon.
The sealant itself was and is still tacky and pliable. In my opinion it has done the job well and I shall now be deploying some more of it when I rehang my front wings, to seal between them and the inner wings.

I may also use some on the gearbox tunnel cover, what do others think?
Best wishes,
Mike.
