If you ask the hydraulics store specifically for suction hose they will know what you need.
My '85 FC had 5/8" suction hose original to it, I was able to change both fittings, pump and reservoir to 3/4" for better flow. I obtained a new fitting boss for the back of the pump from BAB power steering in California that had a 45 degree angle 3/4" fitting. The original was 90 degree 5/8".

I am pretty sure I replaced my hi-pressure hose with single wire braid R-100 hose. I remember the pressure hose as extremely difficult, done from the top with a wrench heavily modified for the job. Section of a box end cut out so I could slip it over the hose like a tubing wrench.

I believe I also added a 45 degree JIC swivel fitting to the back of the pump to make it a much easier angle to the hole through the frame.

I think the improved suction line made a big difference in my rig. Of coarse all the changes were done at one time including a new sump filter.

Here is a pic of the pump fitting.
