Hey all. Few questions:

What size are the gears? 21mm? 26mm?

How does it work, and what does the secondary external setup do?

Is it possible to use the external portion to scavenge sump oil and use it for either a piston squirter setup or valve spray bars?

There are three versions; small passage flat cam, large passage flat cam and large passage dish cam. The oil pump works like any other oil pump. The outer part pumps transmission fluid.

I don't have one in front of me but I believe they are 26mm gears on the large passage and 21mm on the small passage.

Or maybe use for a turbo oil feed.

I learned the pump relied on gravity from a canister in the wheel well full of ATF. I wonder if it can pull from the T3 block-off area. It also can't be modified on the body for full-flow, but I think I can tap further upstream.

You can adapt the outer "autostick" part to another pump body, the gears press on/off the shafts fairly easily. I did it with a Berg pump, intending to use it as a turbo scavenge pump. Went as far as fabricating a steel intermediate plate to provide an outlet for full flow. Project went a different direction and never ended up using it.

the gears in the outer autostick section are very small ...maybe 9mm? if i get down to the shop later i'll measure one

I'd appreciate it. Trying to buy one now.
