Danhaki Fuel tank
I recently purchased a plane that has a Danhaki fuel tank in it. The tank uses plastic tubes press fit in holes in the cap/stopper. These are used in this airplane for a vent tube and a fill line. I removed the fuel tank and found the fill line tube no longer pressed into its hole. So far the vent tube was still in place. I would like to use some sort of glue to insure that they stay in place but am not certain of what glue to use and just as important what glues to NOT use. This tank will be used for gasoline/oil mix. How should I insure that these tubes will stay in place under vibration and exposure to gasoline/oil ? And like I said before, what glue or glues should I for sure NOT use ?
Thanks
