Ok, roughly,
My BA6 still works, so I have not removed it,but my manifold hetaer
boxes are all rotted out. I just capped the ends of the heater boxes,
but some hi-temp tubing pointing out the back would probably help it
run cooler (Private planes use a special hi-temp flexible tubing from
the muffler to the cabin heating system, this stuff may be able to
take the heat). Actually, removing the heat exchangers all together
may be what I'll do, as they are no longer needed, and not usable
anyways.
You have a small fuel pump and a few electrical connections for the
BA6 (safety switches) that will have to be secured, and you may want
to pull the fuse/cut the circuit breaker for the BA6 as well to keep
the fuel pump off (or just pull it and cap the line, it is drawn off
of the fuel yank before the engine pump, so it is under low gravity
pressure).
Hope this helps. ...JMM
