Help! Where do my burst discs go on my tank?

[rawbutter]

I've got a problem.

I received a MacDev tank regulator in a trade, but for some reason, when the tank reg was removed from the tank, both of the burst discs were unscrewed. Now I don't know which burst disc goes where on the reg. I have a 7.5k disc and a 1.5k disc.

So, if you have a MacDev tank, you can really help me out. Just look carefully at your tank and see which burst disc goes where.

Here are the choices.
On side A, the hole for the burst disk is closer to the tank.


On side B, the hole is closer to the top.


Please no guessing. If I put the wrong disc in the wrong hole, then it's going to blow the low-pressure disc when I fill 'er up.

The first two people get +1 internets for helping me out. (I want at least two responses so I can be extra sure.)

I was going to cheat and use the manual, but I can't find one. I guess you tried that. I'd bet they took them out to use a strap wrench to get the reg off.

In case you don't get two good responses:

The high pressure side shoud be the disc that is lower on the reg and closer to the bottle. It has the smaller vent as well.

Yeah... I tried looking for a manual too. I even emailed MacDev (but that was two days ago, and they haven't responded yet.) But thanks for the hint about the high pressure side.

Anyone else have a MacDev tank they can compare to mine?

High pressure is on the tank side and low pressure is on the gun side.
Closer to the tank for high and closer to the gun for low makes sense.

Awesome. Thanks.

I have a 68/4500 pure energy tank w/ 2 burst discs and that's how it's set up.
7500 disc at the tank and 1800 disc on the gun side.
