Can anybody help with the AF pump?
My damn pump has quit working.
When I attach a bottle and start to fill it, as soon as pressure starts to build the pump will not pull in any air. On the upstroke, the pump is creating a vacuum and I cant pull it up more than a few inches.
If I take the bottle off, the pump appears to work just fine.
I have taken it apart as far as i dare, I just do not see what is plugging up.
Anybody?
I have looked till my eyes bleed for a drawing on pumps like this, I cant find one. Anything might help.

Riff, your in way deeper than I can even imagine, obviously you checked that first, sorry I couldn’t be of any help…
With that said I think your a prime candidate for a carbon fiber tank system…! Also I think I may be in your boat here sometime soon (if your pump was new when you got it).
How many fills did you get…?
Send it back to AF and let them sort it out.
Or buy a Hill so you can rebuild it yourself when needed. 😀
No, there is a little rubber ball that acts as a check-vavle held in the cap by the small shaft. The shaft is held in place with a small pin. This ball is in good shape, and rolls around in the pocket and doesnt get stuck in the hole.
Many o-rings in there covered in grease. Wiped them all down, cleaned up as much as I could find reassembled and still the same thing.
I havent removed the lower half of the pump yet. Being a 2 stage pump, Im sure there is something plugged down below. A lot of grease has run out of the pump since I bought it.
I just dont know if anything is going to fall out of place when I pull it apart. I seem to have bad luck with that sort of thing.
Aggravating the stupid thing pumps until pressure builds. A few weeks ago it started to act like this when I hit 2500 psi, now it starts at 500.
You may have done this, but the intake is under the handle on the top, has anything wedged itself in there…?

I got maybe 50-70 fills? At about 200 pumps per fill (going from roughly 1800 – 2800). Guessing about 10,000+ strokes.
I called AF about it, they asked me if I had it apart. I told them it unscrewed itself on the top half, and I had put it back together(which did actually happen when it was new). Bitch told me I voided the warranty so I said FU and hung up.
I bet a Hill is built very close to the same thing. Maybe I can find instructions somewhere on rebuilding one.
I posted in another thread somewhere that HPA tanks are a no-go unless I can talk the fire chief into filling a tank for me. Its doubtful as he is a shithead. Butted heads with this guy a few years ago over a fireworks fire that wasnt my fault, but it was on my property. I pushed his ass across the burrow ditch into the road and warned him to stay off my land. I almost got charged with assault but one of his cronies actually stood up for me, then the poor bastard got fired for it.
Like I said, probably not going to fill for me.
