Hiball, how is that different from the FJ jacks? Curious if we could take the HF body and add the FJ pump, IIRC it was like $170 for a new pump that just bolted in. If they truly share the same frame it could be a way to get a decent jack for less than new Snap On price. Just another one of my hairbrain thoughts.
I didn't put a lot of thought when I looked at the schematics, as they are very generic in regards to the hydraulic pump components, but they both did only show 2 valve plugs on top for both models. Of course, since you have the snap on model you can verify by looking at the top of the block, if you only have 2 plugs, and they carry the "do not adjust" stickers. I'd confidently say that both jacks utilize the same "hydraulic valve system", Not necessarily the same Seals, but the delivery system.
I did spend some time at HF yesterday and gave the Jack a visual once over, I thing I didn't like was the lack of valves on top of the Jack. I'm not a big fan of the cartridge type valve, and since there where only 2 valve plugs, I'm wagering one is the safety overload and the other is the high side bypass.... Sigh, this tells me that more than likely Each pump carries a cartridge under it.
