I think the sender unit might be faulty. Carry a spare can and keep track of how much fuel you've put in and how many miles you've done until you get the problem fixed.

good idea mate but at presant the speedo does not work cable has broke at the gear box end.

The cable isn't hard to change, though you should check that the speedo mechanism isn't seized because that might be why it has snapped.

I use a map to judge distances. You should be able to get 200 miles from a full tank.

You haven't said if it has a nut or a push on connector yet?
It is possible to fit the sender unit into the tank in the wrong position which means that the float hits an internal obstruction and cannot give a
full reading. Looking from the rear of the car my sender terminal (a push on type) is on the right of centre and points to 3 oclock. Assuming that the nutted type is the same this could be his answer.

i will get a pic for you as it is a push fit that bolts to the sender ????

That is a bit ambiguous so I look forward to the picture.

OZZY, I have checked my late type push-fit sender and it is a blade which emerges from the centre of the sender, is bent at a right angle pointing to the right at three oclock looking from the rear of the car.
There is no nut clamping the push on terminal which would suggest that you have the nutted early type but the nut has been used to add a push-on fitting. If this is the case then it seems that you have the correct sender unit for your type of fuel gauge so, IF it is fitted to the tank in the correct position your fault is probably inside the sender.
