There is another tread on here:
https://www.defender2.net/forum/topic90834.html Some cut an inspection hatch in the panel to get to the tank, i would do the same. There are dimensioned drawings, do a search. Otherwise, unfortunately, the tank has to be dismantled. The first step would be to test whether the transmitter works (measure). Otherwise it could be a problem with the cluster which can be repaired by special shops. Edit: I did a search and found a german article, no need to understand it, look at the pictures. In case your sender is faulty this would be my route to go. I would not trust the dimensions and figure them out myself

Thank you Hornet.
I have found some instructions on how to check fuel sender resistances from Martin, Site Admin, from Nov 2022. I am posting his instructions here so I can find them again easily. "2.2 resistance spec is 50 Ohms full, 1000 Ohms empty. You could also check at the grey chassis loom connectors under the right hand seat. At the cluster you want to measure resistance between pins 8 and 31. For the chassis loom, disconnect the grey connector pair, and on the connector with male pins (this goes to the tank) test between pins 6 and 7. Wire colours are green with orange, and yellow with purple. Martin" From reading various threads, it sounds like the fault could be anywhere between the sender, the fuel pump, and the gauge, probably a corroded connector somewhere. The gauge normally fails open circuit, e.g. showing empty, and it doesn't seem to have those symptoms. We shall see. I will report findings back here. The problem is, it is currently working fine, i.e. showing a full tank, so hard to test until it plays up again. Puma 90 XS Station Wagon in Keswick Green 2012 2.2 Tdci |

48 -50 litres to fill up with the light on is what mine does. The same with the gauge going to 3/4 and up to full after a bit - its done that once 8 years ago. The sender unit is in the top of the tank so you will have a bit of difficulty removing it. I wouldn't worry but its your call. 1953 80"
