(DG) Type 3 Hydraulic Pump Mounting

Hello,

I'm installing a Type 3 Linear Hydraulic system on my Irwin 52. In order to locate the pump on a horizontal surface and at the same level or higher than the ram, I can't run the hydraulic line up to the reservoir without adding more fittings, which I'm having trouble locating..... It is under the aft bunk.

My question is, can I mount the pump on a vertical surface? The pump would still be horizontal, but rotated 90 degrees.

Thanks in advance for your assistance!
