Are the O rings used on the main & aux tanks

Thank you in advance.

Also, if my gas gauges aren't working, would this be the time to address this issue too?

Same oring. Great time to trace fuel gauge issues.

Why do they look so different? Is one missing the Sending Unit Lock Ring?

 

[tasker]

they are the same....let me know if you can't find them...I have a bunch someplace!

They are the same, I had trouble with the flat Orings sealing. So I used actual Orings just got a couple approved for use with gasoline. Viton I think.

I have good luck with the Ford rings. Grease them up a little and bend the locking tabs a little to provide good pressure. Ford dealer will have them in stock for about $1 each.

If you can I would definitely reuse your stock locking rings.
The aftermarket ones that I've tried using suck.
