So I just recently purchased a used tpx, now here is my problem.

It works when a remote line is used but when C02 is used the co2 just leaks out the remote adaptor.

I've never seen this happen before, help?

Do you mean as you screw the cartridge in, it leaks out all of the co2?

When you put a 12 gram in, and puncture it, the air leaks from the remote line adaptor.

Is the pin still in your adapter? Take the adapter out and shake it side to side, you should hear a rattle.

Like an HPA tank fill nipple, there is a small pin inside that gets pushed out of the way when there is input pressure, and it closes the nipple when there is back pressure. If that pin is missing or the Oring is worn out, you are just going to leak air.

You can check the Oring on the pin by simply removing the nipple from the end of your adapter.
