Step 1: Separate the eight F-01498 Fuel Line Brackets as shown in Figure 1. Step 2: Fabricate a wedge tool as described in Section 5.4 from a scrap of VA-140 Trailing Edge. Step 3: Rivet the eight F-01498A Fuel Line Brackets to the F-01438-L & -R Cover Ribs as shown in Figure 2. Use the wedge tool as required. The larger slot in each fuel line bracket must be on the bottom. For the two middle brackets, place the manufactured head of the rivet against the bracket and create the shop head against the cover rib. For the inboard and outboard brackets, place the manufactured head of the rivet against the cover rib and create the shop head against a washer (so that the washer protects the bracket). See Figure 2.
