These tanks are made for turbine powered aircraft. The FAA requires more lightning protection for Jet A powered aircraft.
Externally, these tanks look similar to what we provide for other 210s. However, the tanks are made with a layer of aluminum mesh sandwiched between the layers of fiberglass. They also have an aluminum roof plate which attaches to the filler neck underneath the fiberglass which grounds the filler neck to the aircraft. The tanks have composite fuel caps and quick drains and an elaborate electrical bonding system for added protection against a potential lightning strike.
The capacity is 33 gallons total, 32.5 usable.They bolt onto the end of the wing and replace the factory tip. The overall span is increased by 26 inches which results in a better climb and above 10,000 feet, we usually get reports of an additional 3 or 4 kts in cruise speed. The tank has it’s own filler cap and quick drain valve. We ship the tanks in gray primer so they must be painted to match the wing.
Installation is very similar to other 210 models. The close-out rib is removed and if you have strobes, the transformer is re-located to the inboard side of the rib. New holes are drilled in the wing skin and our tank/tip is bolted in place.
The next step is to run the fuel line inboard to the part of the wing where the strut attaches. The transfer pump is mounted here along with two check valves. The fuel line is then run inboard to the main tank. For rubber cell mains, the fuel enters through a tee fitting in the door post into the fuel line that runs from the mains down to the engine. For metal main tanks, a bulk head fitting is installed in the side or top of the main tank.
Gauges and lighted rocker switches are then mounted on the panel, pedestal, or over the doors. Apply the placards, fill out the 337 and you’re finished.
The kit is quite complete including tanks, caps, mounting and plumbing hardware, transfer pumps, check valves, fuel line, wire, switches, gauges, fuses, installation drawings and STC. You supply some PRC sealant if your main tanks are metal.
Local installers complete the job in 55 hours but if you have someone do it that has never done one before, it will probably take 70 hours. It’s not an exotic installation but, done right, it takes some time.
