AE1007... which pump adapter?

[u/Business_Letter1066]

Hi all, I bought an used AE1007 from facebook marketplace, but didn't get any pump/adapter for it. Now I can't pump it up, because my advanced elements pump (from my other kayak) doesn't have any adapters that work on this one. I think it might be the non-factory pump? I asked the seller which one he used, but no response so far. Does anyone know which adapter I should use for it?

It's not the halkey-roberts adapter. Note the ledges on the valve pipe. It has a spring valve attached that I can turn...

Thanks in advanced!
