I have a Bitspower D5 Mod Kit with Z-Tube reservoir setup. I recently purchased Bitspower 16mm hard tube compression fittings and they seem to be too large to use with the mod top. On the mod top, the inlet and outlet ports are too close together to fit two 16mm fittings, or even one 16mm fitting and a plug.
Do you have any recommendations to make these Bitspower products work together? Different orientation, or parts I can purchase that will work? Thank you for your time.
