Attached left fuel tank

Fresh back from my work trip to Germany, I was ready to attach the fuel tank to the wing. First, I wanted to check that all the bolts are torqued correctly on the fuel sender cover, but I wasn’t too sure about the correct torque value. The screws provided in …

Fuel tank leak test passed

After the required minimum 3 days elapsed to allow the sealant to cure, I was able to perform leak tests on my left fuel tank this past weekend. I closed off the vent and fuel supply fittings, and then used a bicycle pump tethered to the fuel return fitting via …

Starting Right Fuel Tank

Since I have all the fuel tank build steps fresh in my mind, I’m building the other one now. It took me about 14 hours to build the first one, not including leak testing and remediation (if needed). Let’s see how long it takes the second time?

I guess I’ve been distracted a lot lately, as I’m making very slow progress on this fuel tank! I think it’s partially because I’m afraid to work with the sealant, which is messy and has a 2 hour working time once mixed. I’ve also been doing a lot of reading …

Fuel tank breather lines

Today’s task was to create the breather lines for the fuel tank. I’ve had the tubing and some of the tools for a while, but I needed a smaller tubing bender, which I just recently received. Here’s what I used: 6061T6 TUBE 1/4″ X .049 4FT from Aircraft Spruce OTC …
