Father-Son 1974 Duster Project

Went for a cruise to AlV’s house to check out his projects. Had a great visit made a couple carb adjustments. Headed home, got a mile and ran out of gas!
I thought the gauge sender had an issue.
Al came to rescue me then I filled the tank and discovered this!

The dreaded fuel pickup locking ring!!!
Hope it’s just loose.
Drove the car to work today to run the fuel down some more. Another thing to work on...
