Tata may be, but there are a lot of pattern parts to choose from. Also, if need be, it wouldn't be difficult for me to make my own fuel tank.
Between them and all the domestic parts that fit I'm not terribly worried. If I was I wouldn't own Series Rovers. LOL
Discontinuing parts after they are out of use for more than 10 years is a policy that fully enforced by the BMW owners. Parts support for 10 years is a legal requirement in some countries and modern bean counters are not spending a pence more than required by law in the markets they are in.
So yes, Disco I and Range Rover Classic parts are being discontinued as well as parts specific only to US spec D90s. The usual aftermarket suspects are not entering the market for these vehicles with pattern parts as was expected.
And since Rover got rid of the tooling for the GM V8 series of engines, quality parts for them are getting harder to find. And it doesn't help that the V8s made for the 1995 and newer models have a much reduced expected service life than the earlier V8s.
Everyone expects you to move up to the next newer Rover every 10 years. It is a pity that the LR3s & newer are nowhere near as rugged at the Discos & RR classic. And that the newer computers work overtime to keep owners from servicing their own vehicles. Nothing like doing a trail repair and having the computer immobilize the vehicle somewhere far away from tow truck access.
If I were a Disco fan, I would buy the nicest 1994 Disco I could find, Fill the garage full of '94 and older Disco & RR 3.9 engines and the back yard full of '94 discos for use as part donors.
But not being a Disco fan I just keep my 50 year old truck going with a combination of newer Series parts, Defender parts and parts off American trucks.
The recession has taken out a lot of the suppliers of Series aftermarket parts but luckily for us Series owners a lot of newer Defender parts are bolt on and being mostly emissions testing exempt, we can choose different drive train bits as needed.
But I think the days of Disco folks are pretty much numbered. Already a lot of enthusiasts are junking Disco Is and replacing them with Disco IIs. What happens after 2014 when parts start becoming NLA for the Disco II?
Us Series folks are likely to start losing access to factory Defender parts around 2024 but thankfully there is a lot of aftermarket support for these vehicles and hopefully will remain so.
