Hi meanmf:

Congrats on being close to lighting the burner.

We operate a Jet Cat 120,Use Jet A with prist from a FBO

Filter out of the can,to tanks,filter header tank (Ala Bvm),filter before pump with custom filter which contains an auto gas filter,then after pump with another of the custom units.

Always store fuel in dark area,constant temp,

In short we are pretty picky about fuel source,storage,handling and filtering.

Seems to work for us.

Good luck...rolling out.
