I have Benjamin hand pump used about 1 year and now everytime on the upstroke it will suck air the wrong direction. Anyone know what O-Ring will fix this or do they sell parts. Seems like bad 1 way valve somewhere

I had the same problem. I sent to repair. Came back, work a bit. But the problem came back.
So I went to Amazon and bought a generic, Chinese-made hand pump for $80.00. And has been working since 2017. And the pumping action is still smooth to this day, unlike the Benjamin.

You can do a google search for that condition, I think it is a fairly easy repair. The search can lead you to parts sources as well.
