When you say pressure hose, do you mean the one from the stainless pipe to the pancake pipe? the one with the crap o-ring fitment?
If so, I sorted this leak out by removing material from the lugs on the stainless pipe, so that the o-ring sits further in and seals better, then with a bit of jiggerypojery with a small ball-pein bent the lower lugs to "clamp" the pipe tightly into position.
