After mounting the winglocker wall and the upper reinforcement angle I continue with fueltank and it´s brackets. Bolt holes in spars were not in right dimension, so I drilled them to 6,5 mm. Then installed grommets and fuelpipe, but hole in no 1 center rib was not exactly right. I enlarged the hole and use a 22 mmm grommet instead of the 18 mm. On left-wing I will leave no 1 rib undrilled, until all ribs are connected. Now it´s time to drill holes for fueltank ventilation and fuel level sender. But first I have to buy 2 different types of Locktite. A decision about fuel-return line is also an important issue. Now it´s time to install it, but on one or both fuel tanks? With return-line to both tanks there is also a need for another, more expensive, fuelvalve.
