Since we are on the subject of the Electrol 750N Powerpak used on the -2 & -3 birds, I have a question that even the very detailed post from 2008 did not answer... Basically what is the correct procedure to maintain the proper fluid level in the system (after it has been initially filled)? Can all fluid replenishments to the system be added to the firewall reservoir and from there the system will keep the correct fluid level in the Powerpak reservoir? Clearly the reservoir on the Powerpak contains the working supply of fluid, but how is the fluid regulated between these two sumps? If anyone has this figured out I would really appreciate the feedback! --Rob
