The fuel sending unit most likely is shot.
I have a spare unit if you want it. Half hr to replace.
Remove back seat, pull off cover, remove ring harness and hose, pull pump, reverse the process.
I have had my pumps in and out more times than I like. The cluster is an expensive part, let's try the sending unit first.
Can test the sending unit with a meter.
No worries Paul, we will get it fixed.
