Be cautious when using zip ties insdie a fuel tank. A guy at our filed crashed his 40% plane with a DA-150 on the front of it because he used zip ties that weren't compatable with gas and completly disolved inside the tank. The clunk line fell off the tube and engine starved for fuel. When he opened the tank he found no zip ties at all, and yes, he knows he put them in there. Not sure what would happen with glow fuel.
