I pulled the plastic guard and thoroughly scrubbed the tank, it’s in good shape, inside and out, but yeah there was a ton of crud resting under that guard.

But as far as that breather on the second port, does that look kosher?

It may have lost it ground thru the sending unit
locking ring?
You could remove that ring a clean everything up
Then put it back and see if it works.
That's the vent they used back then.
I had the same type on some of my trucks.
Make sure it is clear (so it can vent).

Awesome thank you. Yeah I had never seen one like I before so I wasn’t sure if it was stock or not. I’ll give it a good once over and throw it back together. The sender itself looks to be in pretty good shape, so hopefully once everything’s cleaned up it’ll work!!
