My pump is much more powerfull (pulse wise) than the stock pump. It buzzes
loud enough to hear above the engine at idle (2,000 RPM). I was not aware of the
above warning.
Thanks for the
comments Lynn. One other question came to mind though. I have a
remote sump on the single rotor, so the line from the stock oil pump will
be "suction" to some extent. I believe you have a dry sump
system, so you probably have the same situation, only worse perhaps. Are
you using these Aeroquip hoses for suction as
well?
The spec
for suction service on a -12 size is 18" of vacuum. In a quick
search, I wasn't able to find a spec for normal AE601/701 high pressure
hose. Maybe it's the same. I'm not quite as worried about this,
since the head pressure will be about the same as if the engine had a
normal pan, and I'll run it plenty on the ground to make sure it's
OK.
