We find gascolators on certified aircraft. But - are they needed on our experimental projects?
Many times we are left on our own to make decisions about fuel plumbing options in our homebuilts because the engine choice is left to us - not the aircraft designer. And with each engine choice comes a variety of fuel plumbing decisions. One of these is whether to use a gascolator in the fuel system.
In this video we examine the design of a popular gascolator so we can understand how it works and what benefits are achieved in using it. By feeling comfortable with these details, we can make an educated decision as whether it is a good choice for our aircraft fuel system.
