The caps are not glued on but rather sealed using an aerospace grade pliable fuel cell sealant. When gasoline comes in contact with the sealer it becomes pliable and will flex without cracking. Removing the cap to replace the clunk line in the future is easy once gasoline has been in the tank. #2 Why are the clunks not all the way to the back of the tank? Gasoline Fuel line no matter what type expands once in contact with gasoline. A six inch fuel line will grow on average about half of an inch once submerged in gasoline. If the clunks were too close to the back of the tank this expansion would cause the clunk to hit and restrict free movement. Second reason is the felt filtered clunks we use do not suck the fuel in from the back. Instead they draw fuel in from the sides. Basically there are like a sponge and will suck out every drop of fuel in the tank. Yes we have flight tested this many times by running the tank dry flying hard aerobatics and after landing there is only vapors left in the tank. #3 Can I use these for smoke? Our gasoline tanks cannot be used for smoke due to the filtered clunks element not allowing the higher viscosity smoke oils to flow past the filter. We have tanks built just for smoke available on our products page. #4 Why are you not using Tygon fuel line for the clunk? Years of testing and experience tells us that Tygon brand tubing sold to modelers gets hard and brittle in a very short period of time. After many different bench and flight test I have found that the fuel line we provide has superior lifespan over Tygon. No fuel lines last forever but I want to provide the best product possible at reasonable cost to you our valued customers. Of course we are always listening to our customer’s feedback and learning new ways to possibly make our products better. Hopefully this information will help everyone understand that Fourtitude R/C tanks are not just something that we just decided to slap together and sell. The development process has taken over a year with hundreds of hours test flying to get the product you see today. Thanks for the tremendous response about Fourtitude R/C and we hope to see you at a fly in sometime soon!
