Hello.
Yes that could be the case.
Disconnect the the electrical connection, but be careful because it is probably corroded and the wire or conector could brake during the disconnecting.
After disconnecting clean the male and female connectors + spray with WD40, 5-56 or best of all 6-66(the marine version of 5-56).
If the connectors are corroded it could be better to change them and reattach new fresh connectors after cutting of approx 1 cm of the wires.

Best of luck.

And if that doesn't work, check the connection (the large multiplug on the right hand side) underneath the instrument panel, it's particularly weak and if it's been interfered with you can often find poor contacts and even breaks in the printed circuit.

How do i connect the new connector?and where do i buy one?

Biltema market a kit with all sorts of connectors (kabelsko) including the kind on the fuel gauge unit. The kit is standard, cheap, and includes a cutting, stripping and crimping tool. You'll also find these in some petrol stations, electrical and hardware stores.

Correct me if i am wrong, but as i can recall the connector in question is a special type just for VW. If that is the case you have to buy it from Møller. If you have a soldering iron you can also dissassemble the old on, clean as good as possible (remove the corrosion), cut of aproxx 1 cm of the wires and then reattach with soldering.

Yeah i have wondered about that the wires which there are two of go into a plastic casing and as far as i can see can not get them out of that plastic casing manually.
I am also wondering if it is the connector on the actual diesel tank itself??
if somhow do i remove that or get over the problem.?
It is starting to get a bit complicated for a novice like me

Maybe Andrew could take some pictures and highlight the items in question.
It is always easier to discuss when "we are on the same side of the table".

is this true or does biltema kit do the job???i have a 91 syncro with 1600td motor,not sure if that makes a diffrence though??

My mistake, Eskild is right, the connector on the tank is not a standard one. I'll see what I can do with some piccies tomorrow.

ok thankyou,so it is off to the garage then

also can be the plastic flouting boye who is inside the tank is broken and full of diesel so take the tank down and change that boye
