Check your grounds for the dash to see if they are corroded or the wire is broken somewhere.

I had the same problem and installed a new sending unit and all was good.
I have a 90 as well and I have seen this on one other 90.

In the gas tank, accessible by removing the filler neck. Not tough to replace, but keep all flames sparks away.
