Modifying RS-340 Regulator

[fireinc]

I have a Tusa RS-340 regulator. I would like to add a Miflex LP hose with a right angle/swivel connector to the second stage. This would allow me to direct the hose under my arm. I am having a little difficulty identifying the correct size of adapter/connector I need to make this modification at the second stage. I also wonder about the thread size of the LP port on the first stage. Any input would be appreciated.

Hello,
The TUSA R-300 first stage is equiped with Two H.P. Ports (7/8"), Three L.P.Ports (3/8" standard) and one High Flow Port (1/2") for the primary second stage. The primary second stage hose uses a Standard Regulator Fitting on the swivel end at the second stage connection. The swivel can not be removed from the TUSA hose.
Thank you for your inquiry,

I have the 340 yolk. When the tank valve faces the BC and the primary and secondary hose are on the right side, the primary hose is under the secondary, opposite to the way it should be. How can I reverse this? Also there is no LP port labeled SS as indicated in the manual.
