Dear all:
Thought this might be helpful for people flying the Trex 700.
I know people are talking about using the outer hole for fuel outlet and seal the center hole. But recently I encounter a problem after changing the fuel line inside the tank. the center sealing rubber leaks after times when you remove.
Therefore I came up with a thought of using two fuel outlets (see pics) This helps to prevent leaking at the center hole now are "enlarged" by the nipple. All you need now is to block it. Or best if you are not using header, you can use it as "refueling" inlet. To facilitate easy removal of fuel tank, I file off part of the main frame to allow the protruding nipple to just went thru without having to take it apart.
See pics. I find that this is very clean and easy mod. Plus if you need to change fuel line inside the tank this is an easy fix.
