Please check my rig.

So basically, you lose the T-coupling, attach the long hose where he has the T-coupling and the rest kind of falls into place... right?

Not sure I saw the T coupling in the pics??

I thought that the hose with the yellow hose protector was the long hose, it looks like it's connected to one of the standard LP ports on the turret. This just needs to be relocated to the port on the end of the turret, and the first stage rotated 30 degrees clockwise and it should be fine.

You can just make out the LP port in the end of the turret in this photo of a MK25 first stage:

Ach.... Yeah, now I see it. If you look back in the second picture on post #7. I thought the LP inflator hose and the octopus (the yellow one) were both attached to the bottom of the turret with a T coupling but it wasn't a T coupling, it was the turret.

But now I understand what you mean. Thx.
