Hi Peter,
Many people on here don't realize that there were a minor number of hydraulic pumps that were a different configuration
than most. I have one just like yours and had to get creative. I basically had to get an AN T fitting and change the
way the plumbing comes out of the pump. I've attached a picture.

Subject: REFLECTOR: AN fittings and the RG pump
Hi all,
Working on my RG pump over the weekend, I discovered a weird problem that I was wondering if other folks had. The pump has a swivel fitting attached to it followed by a T fitting with a nipple and female NPT threads on the run and another nipple on the leg. The T fitting gets set up so that the runs are oriented vertically so that the pressure switch goes on top and the aluminum tubing comes in from the bottom.
The problem is with the hydraulic fluid reservoir. It projects out too far and prevents the vertical orientation of the fitting. See picture.
It was suggested to rotate the reservoir which only moves the problem to the back side preventing mounting to the canard bulkhead. The hole patterns prevent 90 degree rotation.
I think I could kludge something up with some AN hardware (a few couplers) - but it feels a bit like a hack. Just wondering if anybody else has encountered this and if so, what's the solution?
Best,
Peter
