I will never understand why my fellow jet guys install filters in their airplanes. My fuel gets filtered going into my five gallon fueler. There is a filtered clunk in my fueler, and there is an automotive filter going from my fueler to my airplane. Once on board, there is another automotive filter inside my UAT.

From there, the only thing that can go down my lines into my turbine is pump parts, rotted fuel line parts (assuming my fuel lines will someday not last forever), or solenoid parts.

Considering how unlikely it is that one of those sources could end up in my turbine, I have never installed an onboard filter. Figuring anything remaining was small enough that ingestion in the turbine was no big deal.

This by the way, is a far more acceptable place to burn trash rather than the possibility of having a 5.00 filter onboard cause me a bubble flameout or a debris flameout and losing my investment altogether.

But that's just my humble opinion.
