Completed steps 2-8 page 27iS-07
Step 2: Straightened 42 1/2 in. [1079.5 mm] of ATO-035X3/8 tubing. Made the F-12127A starting at the tank end by making the 89° bend as shown in Figure 3. Step 3: Placed the nut then the sleeve called out in Figure 3 over the end of the tubing and then flared the end of the tube. Step 4: Fed the bypass end of the line forward through the snap bushings shown in Figure 1 to the Bypass Fitting Assembly Step 5: Temporarily attached the F-12127A to the FLF-00017 as shown in the detail view in Figure 1. Added slight bends at bulkhead locations as required to align the fuel line with the snap bushings and the F-01276C-1 Systems Blocks. Laid the tube in the recesses of the F-01276C-1 as shown in Figure 1. Added a slight curve to follow the curvature of the F-01276-1 Bottom Skin. Marked the forward end of the F-12127A at the end of the AN816 fitting in the Bypass Fitting Assembly. Added 0.100 in. [2.5 mm] to the measurement from the end of the fitting to account for the flare as shown in Figure 2. Step 6: Detached the F-12127A from the FLF-00017, slide the tube back, and cut off the excess tube at the mark. Placed the nut and sleeve called out in Figure 1 over the bypass end of the tubing and then flared the end of the tube. Step 7: Attached the F-12127A to the Bypass Fitting Assembly as shown in Figure 1. Step 8: Reattached the F-12127A to the FLF-00017 as shown in the detail view in Figure 1. Checked for clearance at the aft most snap bushing.

Step 1 (Prefabricated Fuel Tank): Installed the VA-265 and the T-01233, shown in Figure 3, as described in Section 26iS/U. Step 2: To fabricate the F-12127K, straightened and cut off 25 1/4 in. [641.4 mm] of ATO-035X3/8 tubing Step 3: Measured 21/32 in. [16.7 mm] from the tank end of the tube and marked the end of bend line. Measured 1 5/16 in. [33.3 mm] from the tank end of the tube and mark the start of bend line. Flared the tank end of the tube. Made the 38° bend by referencing Figure 2
