Mine is leaking from the bottom, not sure where from yet.

Been researching rebuilding the pump. Almost all the time I would do things like this myself. But...

From what I have learned, maybe not.  I saw the rebuild kit, nothing that details where each o-ring goes! I’m good at reverse engineering, but this? 

Options:
1. Buy new pump
2. Send out for rebuild
3. Send tractor to tractor repair shop.
4. Buy new tractor.
5. Rebuild myself.

I know this is going to be expensive.  Cry

What would you recommend?   I live in west Georgia, anyone local for some consultation or maybe assistance with this?

Turns out it was the o-rings on the throttle post. Replaced them.  Did the o-rings on the shut off post too.
