Hi all

I can't find a thread on this , so apologies if it's been covered before

I have a 1990 1800 T D P100 & the fuel guage doesn't work. It just floats up & down as it sees fit with no relevance to how much fuel is in the tank !

I realise this is a very common fault as most of the ones on Ebay seem to have the same fault.

I am assuming its probably the sender unit at fault ? but would appreciate anymore info
