Hey everybody,

I recently salvaged my Airtech 3000 that had been commissioned by RyanMcNumbers. A while back one my friends had tweaked the pump in a way that whenever I pumped it, no air would be pressurized into the tank. I replaced the old Hornet pump with a new one and can now fire the gun again, however it now takes 10 pumps to achieve the same pressure as when before it only required about 4. My theories are that my friend has previously slightly over pumped it or that there is a leak somewhere. Any other suggestions? Thanks in advance.

If I had to guess, I would say that a leaky tank is not your problem. If the tank had a leak in it the number of pumps needed to fill the tank wouldn't change much at all.

Did you change anything else when you repaired the blaster? Did you add a substantial amount of extra tubing between the pump and the tank? Is the pump stroke just as long as before?

All I did was take a new pump plug it and put it in.

That's obviously the reason why it takes so many pumps. The hornet pump has a much smaller air volume.

Triple post!^ But yeah, your right, the AT3K pump is at least twice as wide as the hornet pump. Therefore needing more pumps to bring the tank up to the needed pressure. The thinner pump does allow you to reach higher pressures than the wider one, but it takes longer.

He said that he's using a Hornet pump, though. My only guess is that you need to lube your pump or replace the o-ring.
