[Fot] Question on Accusump Install with External Oil Lines On a Spitfire

[Ed Diehl]

Hi, Bill  and all. I found that one important thing on this installation is to
have a one way check valve in the system to prevent the oil from going two
ways as it leaves the accusump and only flowing into the bearings. Put the
valve on the cooler side of the "T". Cheers and stay warm. Ed.

That is certainly the normal and easiest way to connect an accusump, but not
necessarily the best. Supplying oil directly to the oil galleries seems to
have
substantially improved the reliability and lifespan of my engines--it means
my
engines always have at least 50 or more pounds of pressure in the oil
gallery--even at startup.

Not only is the plumbing greatly simplified, but in measuring the gallery oil
pressure on my TR3 engine I still saw great variation in pressure with RPM
that
you don't see with the accusump directly connected. I could come up with
lots of scenarios that would cut oil pressure with an accusump connected to a
remote filter or cooler line, but only one with a direct gallery connection.

Bottom line, if you're going to go to the expense and added complication of
using an accusump you should get the most value out of it. Going through an
oil
filter adapter plate doesn't seem to do that for me. I'd like to protect
against catastrophes like having that filter rupture or come unscrewed and
still
having bearing oil pressure long enough to get the motor shut down.

the
one coming from the cooler and the stem of the tee is the line going to the
Accusump so what goes into the Accusump is clean, cool oil.

way into the oil gallery passages.
