ASA leak?

[DeuceSV]

Thanks for the help in advance.

I just bought a CP asa that i have attached to my CP drop forward on my emag.
I blocked the one hole to the left so i could have the 90 degree micro fitting in the right hole connecting the microline to my Xvalve.

When I connect my tank, I will screw the front ASA knob all the way out so I can screw in the tank without completing the air circuit. But when I screw the ASA knob back in, there is an air leak from around the knob: not the hold on the left, and not the micro fitting on the right, but the knob in the front.

Any suggestions?
Thanks

Oil the O-rings in the ASA.
