Hey everyone! Above is a picture of the area where the secret oprv's are located on the air max blasters.
The connection from the plastic to the tank just needs to be degreased and superglued in place. (Make sure its super airtight!)

The other oprv is incredibly well hidden I give mad props to buzzbee for coming up with this. But it is basically at the connection point of the blast button to that stupid tubing substitution piece. There should be a little notch that is incredibly hard to notice. basically what you want to do is coat that whole connection in superglue and then wrap it in epoxy putty for extra sealing. We don't want any leaks!

That's basically it besides the obvious one in the pump.
I hope this helped you guys out!

They can leak air at high pressures and I plugged the one in the pump first to test my theory out.
When only the pump is plugged it still leaks from somewhere. I checked everyehere (and i mean everywhere) to see where the oprv's/points of failure areas are. And the only areas I found were the ones in the picture. they're a secondary precaution to make sure everyone is careful and doesn't blow an airtank up in their face.

If you have absolute proof that these points of failure/over pressure release valves (which last time I checked meant a valve/hole that releases air under high pressures) are actually just a leak in my blaster or are areas that don't leak air whatsoever, or if you have your own theory as to why the blaster leaks please tell me so i can test it out. Otherwise don't waste your little type'y time by telling me I'm straight up wrong.

(Also I know you have an air max six you're working on so I would like some feedback/proof. (also sorry if I came off as an ass)

This. I thought the exact same thing. After plugging the pump oprv and doing a rebarreling, I was dismayed to find performance was dismal.

So I went back into the blaster and performed both actions McGee suggested, and performance did indeed rise. These might not be oprv's, but they must have been leaking somehow.

Thanks for the info McGee. Oh, and two common failure points I guess I should tell you guys, the pump shaft and pink vinyl tubing. The pump shAft warped and bowed on me, making it impossible to pump. I sheathed it in some brass tubing, and now it's golden (in two ways). The pink vinyl burst on me fairly soon, so I simply replaced it with some spare fish tank tubing I had lying around. It's much thicker and I've used it to do pump relocations before. It's best to do these actions right off the bat, that way you don't have to reopen the blaster a few times.

Hope this helps!

My pink tubing also failed on me as well, so I just replaced it with some vinyl tubing and now it works fine.
My pump also started to warp and eventually snapped so I'm working on reinforcing the tank, and replacing the old pump with a bike pump. But for now since your pump hasn't snapped yet, I would reccommend reinforcing it with devcon plastic welder or some other kind of epoxy/e-putty combo.

I guess you missed the part where I said I sheathed it in brass. I'd take metal reinforcement over epoxy any day.
