I had the same problem on my 81 924 I cleaned the connector that attaches to the guage cluster and now the guage reads steady.

Roger:

Ok I will do it , thanks.

any other idea ?

Clean and tighten the connections to the fuel sender in the back hatch floor. I found these connections corroded and greatly effected the fuel gauge reading and stability.

I found an air bubble in mine. Burped the system and the needle stays steady.
