Did you get the flight works pump? If you did won't need them the flight work pump has rf suppression built in.
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.
Try running the pumps in a closed loop of JetA1 for 12 hrs on a nominal 1.2v- 2.0v with a filter in order to bed the bushes in and collect any fines of the gears that might block the injectors.
