Tried to post a few minutes ago but for some reason it hasn't appeared on the forum.
I was looking at two tanks on eBay and found exactly what you said, Wolfie - the sender is on the top of the Rover tank, along with a big hole for, I presume, an in-tank pump. The other tank I saw was an earlier one, so I think that's the one I need.
Annoyingly, it's the more expensive one - an extra £13.95, unless I can get the seller to accept a lower offer...
...OK, assuming I have a new fuel tank.
1) Do I need to have it treated internally to cope with modern petrol?
2) My flexible fuel pipes are in all probability, quite old. It makes sense to replace the rear section where the tank connects to the rigid pipe. If I'm buying new flexi hose then the hose I buy today will be the correct type for modern petrol. Do I need to replace the front section too? More importantly, do I need to replace the rigid fuel pipe from front to rear, assuming the current pipe is copper, and if so, what do I use instead?
All comments welcomed...
