Figure 8-1. Additive Mixing Ratio
CAUTION
Mixing of the EGME compound with the fuel is extremely
important because a concentration in excess of that recom­
mended (.15% by volume maximum) will result in detri­
mental effects to the fuel tanks. such as deterioration of
protective primer and sealants and damage to O-rings and
seals in the fuel system and engine components. Use only
blending equipment that is recommended by the manufac­
turer to obtain proper proportioning.
CAUTION
Do not allow the concentrated EGME compound to come in
contact with the airplane finish or fuel cell as damage can
result.
Prolonged storage of the airplane will result in a water buildup in the
fuel which "leeches out" the additive. An indication of this is when an
excessive amount of water accumulates in the fuel tank sumps. The
concentration can be checked using a differential refractometer. It is
imperative that the technical manual for the differential refractometer
