I just confirmed with Vans another error in the plans. On page 31-05 figure 1 shows the AN833-6D (the elbow fuel fitting that penetrates the firewall) clocked up 25 degrees from horizontal. On page 31-11 figures 2 and 3 have very different clocking angles for this same fitting depending on whether you are building the taildragger or tri-gear. The clocking angle found on page 31-05 IS NOT CORRECT. Use the clocking angle appropriate for your build found on page 31-11 instead.
I'll be adding this to the Gotcha sticky.
