So I got a lot of work in today on my tank. I should have stopped 20 min before I did. I think I was tired and made an error in reading the plans and orienting my inboard tank rib. The image below is of my T-703. As you can see I did not have the part oriented correctly when I drilled the first hole for the fuel vent line. I realized my problem and drill the correct hole. So now I have to decide what to do with the bad hole. The way I see it I have three options.
1: order new parts and build the a new rib. (my least favorite and I don't think necessary)
2: Use the bad hole for a fuel return line. I was going to install one anyway but I was planning on putting it up higher on the rib and having it return fuel to the third bay. Anyone see an issue with putting it lower on the rib and working the fuel return line to the top of the tank in the first bay then straight over into the third bay?
3: creating a patch. Cutting a piece of AL to fit over the hole and using tank sealant to close the hole. If I did this would it be necessary to sandwich the rib between two pieces of AL or could I just put a patch on the outside?
Any advice is appreciated
Also while I am at it. I have read about people using HEX head screws to secure the fuel tank access panel. Are those ordered from vans? Anyone have a part number or link if they are from an outside source.
Thanks
