No FW,
I just got the normal JJ pumps, they're not as good as the flightworks/hausel pumps but I am able to test them here at my work, we have a variable voltage pot on one of our aircraft fuel control test rigs, kinda handy! One pump seemed to work fine, no leaks, no probs with current draw and flows could be varied from barely a dribble @ ~0.8v to quite a considerable flow, up near ~850ml/min @ just 5v and was only pulling ~1.4amps. I don't know if this is normal though, but it sounded fine and didn't heat up at all.

The other pump wasn't so lucky, it required 3 amps just to start and leaked badly, I pulled it to pieces and found the small pump drive gear was pressed onto the electric motor shaft just a few thousands of an inch too far, pretty much making it lock up, I "manipulated" it and it now works nicely just like the first one, I don't think they test them before they ship them out, not a good thing but relatively easy to fix. So now I have two nicely working fuel pumps!!
