+2 Fuel tank

I used POR15 (paint over rust) paint on the outside of my old tank and then a coat of their chassis black and I;m delighted with the results.

It isn't the outside of the tank that is the problem. It is the inside in which I have rust flakes.

Yes I understand that, just a commendation of POR products. My tank now has a rock hard coating that looks as though it will last for years.

I have a few flakes of rust moving inside but I expect they will probably stay there and a good fuel line filter should be adequate if they decide to move.

The rumbling operation with nuts bolts inside and turning on a concrete mixer will get rid of flaking rust inside. Before degrease and product to neutralise rust.
Then special resin imho is the best way
The resin seals and sticks anything inside tank.

Well after a couple of phone calls I can say that I won't be getting it cleaned/sealed professionally. The two companies I called each said £300-£325 +vat which is too close to the price of a new alloy tank so I won't be going down that route. Unless anyone knows of a reputable firm in the Midlands who would do it cheaper?
So back to the solution it seems being either I do it with POR-15 myself, which seems a bit of a nasty/hazardous process with indeterminate results, or I buy a new alloy tank. :(

Ok...I have now got the tank out and I have more or less now decided to replace it. Previously I had thought that externally the tank was good but having now got it out , it is quite rusty on the bottom and maybe not worth trying to reseal it.
However in searching the various option for a replacement tank I have been reading about the effects of Ethanol on Aluminium Alloy fuel tanks and Jaguar and Ferrari owners seem quite concerned about this and are seemingly turning to stainless steel as a better fit and forget alternative.
Any thoughts?...
It would be good to hear from any of the guys across the pond where ethanol content is much higher than the UK is used...Any corrosion experiences with alloys tanks in Elans/+2's or any other classic cars?

Thanks,

Alan.

If you're in the midlands, theres one on ebay for £10 at the minute, looks decent enough, supposedly removed for an FIA replacemet. I got mine second hand for £20 and its perfect. Maybe worth a punt?

Just to conclude this thread. After much deliberation and research I have bitten the bullet and finally ordered an alloy tank from Axminster Panels. There were others a bit cheaper but for one reason or another I didn't fancy them.
Hopefully delivery Andy says will be in 3-4 weeks.
In the meantime whilst the tank is out and awaiting delivery the next deliberation is do I change the diff mountings...or do the even more ambitious task of taking the diff out to cure the oil leaks from the output shafts and pinion!.......and so it goes on...All good if expensive fun!

To change seals and bearings on the output shafts you don't need to remove the Diff.

Yes i know I can change the output seals but there is quite a bad leak from the pinion oil seal and although it is a bit risky changing it without a diff rebuild I might have a go.
