HP Brake Hose Leak

[Steve Sherman]

A few weeks ago I replaced the flex high pressure hydraulic line that
runs between the steel pipe and the bomb on my 86 5KTQW.  Used all new
washers, etc.  This cleared up the old leak (oil sprayed all over the
place around the foam cover on the line), however after a few weeks I've
noticed a slow leak at the junction of the new flex hose and and the
steel pipe that goes to the pump.

My question is, how tight should I have tighened that junction?  It had
a new oring in it from the factory, and was sealing when first
installed.  Leak seems to be at the junction itself, although the nuts
still seem tight?  Any BTDT here?

Also, the long thin tube that goes into the outer hoses; which way is
that supposed to go?  The original was equally long on both ends, the
new one came with one end about 1" long and the other about 7" long.
 Which side of the hose (to pump or to bomb) is the long side supposed
to go towards?
