FJ stamped in the end fitting says iit female JIC swivel. Looks like 9/16 thread so that would be 3/8 inch hose with female JIC swivel end. Ask for R16 hose, I'd they have it, R2 is a perfectly acceptable alternative if they don't or they want too much. No need to buy anything more expensive.
JIC-06 wivel end fittings are $5 each and hose no more than $5 per foot.
You can buy pre-made R16 hose assemblies with JIC swivel ends from Surplus Center. Even with shipping probably cheaper than having them made.

Discount Hydraulic Hose has a good identification guide on their site. The threads on common JIC fittings are the same as UNF bolt threads, so I bought a 9/16 and 3/4 fine thread bolt and nut to use as gages for -06 and -08 fittings
