Worked like a charm

It's a good system, still being used today by a few of us out there. No risk of contamination or air in the system when using a mule. Here's a quick video of the operation, most you have probably seen it but it's worth posting again.

All who asked, here is a schematic and parts list for the hydraulic unit/cart I built for my C337A. You can PM me if you have any questions.

It's a female attachment that matches the hydraulic pump. Available from Griswold Aviation in Marshall Michigan

Owen Bell at Aviation Enterprises is also another source for the adapter.
