I have a wet pump on my Navion, and in fact my plane was used by M20 to
develop their wet pump separator (you can see photos on their website).
Currently, I'm using an Airwolf/Walker. One unit handles both the pump
and the breather, and as Gary mentioned, you can open it for cleaning.
The M20 unit never really worked very well on the vac pump. The Airwolf
unit works perfectly.

Since my E225 engine runs hot I doubt that any condensation could
survive
after a flight of any length.


Gary, don't you have a wet vaccuum pump on your E-225?

AFAIK the M20 seperators only work for the breather line OR the vaccuum
pump, but not both. To get both areas covered you would have to install
two of them. The walker (air wolf) unit handles both oil sources in one
unit.

(as an aside, you happen to know that the fuel flow is supposed to be at
full throttle for an E-225 do you?)
