Thanks Red, good thought. I imagine that's not to terribly difficult to replace. Would I need to order the exact part for my particular engine?

Also, small update. Changed out all the fuel lines and something occurred to me. I have three ports coming from my tank as opposed to two, which seems more common. One line is just for fueling, the other two are self explanatory. On one hand, it does makes fueling slighty more convenient, but on the other hand, it's just another part that could go wrong.

The bench test with the new lines is a success. I witnessed no bubbles at all throttle settings! Woot! So of course that means the weather is going to be bad, scattered thunder and lightning and sprinkles. I'm going to fly anyway. I'm using a DX6 Spektrum radio with no antenna, should be ok.
