Check out zoro tools if buying online. I got a 3/4" Wilkerson FR (for right out of the comp, not the FLR on the press) on there for way cheaper than locally or grainger/mmc, and I bet they got FLRs on there too.
Our '92 has an older Norgren setup that's still chugging along and I just got some new o rings for it.
*sorry the above might have been confusing, you want 1/2" at the press for the FLR
