fuel guage issue

Hi guys
Been doing some pre trouble shooting before I dive in. On my 89 flhtp if I have a full tank of gas the gas gauge shows full like normal and after approximately 70 km off the full tank the gauge seems to go down to 3/4 and starts to bounce a bit below 3/4 then starts to head to empty and back up to 3/4 again. After a few more kilometers are gone by the gauge goes to empty and stays there. All this is done while traveling steady on the hiway.
Any thoughts on this before I start in.
Thanks
Lynn

Sender is dirty or broken. Take it out of the tank and inspect it.

Thanks Doc Hess, was thinking the same as it did have an empty tank all winter in storage.

Better to have a completely full tank in storage.

For storing add some Seafoam (not a full bottle) and fill the tank with gas. In the spring you will be in good shape. This is what I do with my motorhome in the late fall (but I add a few bottles). I do start the generator every few weeks but, the gas stays good and everything works in spring.

Absolutely correct and usually I do as a habit but some how it got past me.

Pulled the scensor and it was corroded and only seemed to contact at full. After some fiddling the contact is worse and seems to have some play so reviving is a no go. Looks like the old girl will get a replacement.
Thanks
