1/31/2009 .. Page 18-6, Completed Step 1 to 6 today. I purchased at Home Depot the following items, a tub cutter, pipe deburrer and a tubing flaring tool. After master these items I cut a piece at ¼ X .032W X 63 inches in length aluminum tubing. I then created a flare on one end and placed an AN818-4D nut and AN819-4D Sleeve over the end of the tubing. Then inserted into the Tank as shown in Figure 1 until the non-end of the tubing penetrated the snap bushing in the Vent Line Clip. Installed the AN832-4D BulkHead Union and Nut AN924-4D onto the Tank End Rib T-1003B-R. Riveted and Pro-Sealed the Tank End Rib T-1003B-R to the Tank Skin with the proper rivets and after riveting attached the Fuel Vent Line to the Bulk Head Union as further described in Figure 2. This was not very time consuming about 2.5 hours.
