Bill, I have a knockoff of an accusump on my TR6 using an aircraft surplus
accumulator. I plumbed it into the main gallery when I built the engine in
place of the aluminum plug that seals off the drilling right over the
filter boss. It is a 3/4-16 straight thread ( I have yet to figure out why
the factory would do this instead of pipe threads and allen socket plugs
like the rest of the drillings!). I took a 3/4-16 by 7/8 aluminum adaptor
from Summit and turned down the 7/8 side to a tapered 3/4-16 thread a la
pipe threads, then coated it with JB weld and threaded it in. I had to turn
the hex down to clear the filter boss so I drilled 'spannner' holes into the
hex to make sure I could get it good and tight. It is really in there, and
the larger opening can really flow oil. I know because I left it unconnected
when I spooled up the oil pump with a drill motor! My feeling is that if you
have an oil starvation condition, you want to dump the contents of the
accumulator into the engine el pronto.
