Pumps
Hi Jim,
I just looked at the Maintenance Manual, and while the manual does not show the schematic for the Turbo 337E, it does show that on the other Turbo models, the aux pump is after the selector (and after the strainer). It looks like all the NA models have the pump before the selector (and in the wing), and on the Turbos, your aux pumps are located in the engine compartment, and indeed downstream from the selector valve.
To verify this, just look inside your cowlings - you will see the aux pump. I have attached view from Maintenance Manual. Sorry, I can't find a picture in my files of the pump.
