Pump has been into before. Screw heads show signs so not sure if it happened then or in use.
Is it fubar or will it be ok?
The whole lip is nicked up so I don't think it seals to anything.
Mike - I think you're likely correct about this. It appears the circular lip functions as a guide to secure whatever it is which slides/goes into the orifice itself - more or less evident by the numerous chips on that lip already from many removal & re-installations. Likely the "lip" plays no part in the actual sealing but instead acts as a holder. Good luck.
There is a spring that goes in there but it is much narrower than the ring. Only other thing I was thinking is a bump stop for the diagram ring as that seems to be the only thing that may touch it. 🤷♂️
It definitely doesn't seal anything.
A closeup view of the sectional view of the pump from the book Fig 8-68 shows that feature piece's function is to keep the spring of the fuel diaphragm from walking inside the housing. A small piece missing should not effect it.

Thanks Art
the spring in my pump sits in and below that lip nothing like that picture where it sits around the lip. That's why I was a bit confused.
This pumps been worked on before so who knows what they put in there.
Interesting, I have heard of vacuum pumps as part of fuel pumps but never understood what they were. Thanks!
This was a first for me also.
Alot of the older cars used them to run the wipers apparently. The vacuum side has wipers stamped on it on mine even though it runs the ventilation system.
It's really a simple system once you get past the initial fear and understand how it works.
I've found this video to compliment the verbiage found in many service manuals regarding the rebuild of double action fuel pumps. Regardless of the applicable year, many of the pumps are very similar in design. Once one rebuild is accomplished the following rebuilds come so much easier.
Great video. You can see how that metal (casing) lip on the fuel pump side could get damaged quite easily if you pry on it trying to remove the seal. Instead, he shows how to simply use a screw driver from the underside (vacuum pump side) to pop out the seal w/ a screwdriver. I like.
He has a multitude of videos for other fuel pump rebuilds. I've watched many of them. What I like about the videos is his calming demeanor and voice, no annoying back ground music and pretty easy to follow with good explanations.

Yes it is a good video. Thanks for posting.
Art posted this video on my original thread before I took the pump apart. On the video he states not to damage that ring but never said it would be fine as long as it's not too bad so I got worried when I found mine damaged.
I only had 2 hours sleep due to tornado warnings all night so I guess my worry meter was already pegged and panic set in before I researched it more.
It's together, cleaned up and on the car.
I hope to crank it over in the next few days when I get everything else back together.
Mike - Not sure where you are in NC. I'm on the coast (Beaufort). We received a whopping total of ~1.75". I'm not complaining. No serious tornado threats, no flooding, small limbs/branches down. Next one on the way...roll the dice.
Sorry, that's right I think I asked you previously. I used to drive through Beulaville each week (Rte 24) for a couple years for a customer engagement in FayetteNam. Some years ago when those tornadoes came up from Joplin, Missouri I recall homes & trees turned to matchsticks along Rte 24. Really, really bad remember that one? F3 is a biggie. Remember Mathew and Lumberton entire area flooded everywhere - sad.
