Next is the fuel tank mounting.... before we get into putting it into the plane I wanted to touch base on a couple things.
Many people don't realize that over time your fuel tubing will swell a bit and not fit as tight as it did in the beginning. This is often the cause of an unexpected deadstick... whether it be a line to the engine or more likely your clunk coming off. It is very important to spend the extra time to secure things properly... meet your new best friend, the zip tie.
You will notice that I zip tie every single line on the tank all the way through the fuel T, the filler line, vent line, and on the engine. A dead stick can be.. well deadly if it happens at the wrong time

I went to home depot last summer and bought 1000 of the small 4" ties and 500 12" ties.. for the $40 or $60 I spent I won't have to worry about being in final install mode at 2am and not have a tie to secure things. Some times this leads to taking a chance because you really want to fly that modle the next day... NOT WORTH IT.
