I wish I had saved the name of who provided detailed steps for testing the gas gauge. Thank you anyways. I only had to try the first 2 steps to determine I had a leaking float. When I pulled the sender from the tank gas started leaking out of the float. Must say this was an irritation/surprise as I bought a brand new replacement sender with float 10 years ago. Never expected it to start leaking.
Thanks to the group.
