I decided to eliminate the 90 degree fitting connecting line #2 to line #3 as it goes around the fuselage tube at the left rear corner of the extended baggage box. I merely extended the #2 line and swept it back a bit and rotated the T fitting just above the low point drain003.jpg.
Checked this modification out with Mitch before I did it and he expressed a little concern that the line would perhaps have too much unsupported length so I built a standoff from the lower fuselage carbon fiber longeron tube.
My experience has been that if you're going to have a leak it's likely to be at a fitting and this mod eliminates one - and it's one that would be almost impossible to get to after covering.
