Hi Guys, Here's a few prototype pictures and some info.
The jug's max capacity is a little over 5 Gal / 20L. You can fill it with kerosene up to the 20L marker and add 1 quart of turbine oil to achieve ~5% mix, 1/2 quart to mix ~2.5%, etc... I always liked mixing in the final container, no mess.
The enclosure box is meant to be fuel resistant, although not fuel proof. To be explosion proof (and potentially gasoline safe), there's a great deal of standards that aren't covered in this design. That's the main reason the enclosure box was moved to the opposite end of the jug from that shown in the rendering. Not everyone uses a funnel!
The unit is equipped with an on-board filter that sees 100% of fuel flow when the user is refueling his/her aircraft. It is placed after the pump to catch any debris created in the pump head. Upon reversing the pump to defuel the plane, there's a check valve that allows a large % of fuel to bypass the filter. A small amount will backflow through the filter, but the bypass will cause a net flow of debris out of the aircraft's fuel system. This debris will probably be caught by the filter in the next few fill cycles. The hardware that's exposed on the top of the enclosure box is a set of charge ports (use banana clips or bare wire leads), a standard 5-Amp fuse, a detent-on/off switch (red) and a direction control switch. The on-board battery is a 6-cell NiCad pack. The battery is not fuse protected at the charge ports, just before the switches to protect from internal shorts or a jammed pump motor.
The machined aluminum cap uses an o-ring seal against the tank spout. Just trust me on the importance of that one if you transport fuel in your car!
Bart n' Wayne, thanks for your help in the little design review today.
