If anyone goes to fire up their rig this morning, if you could check this one thing, I'd greatly appreciate it. While it's running, fell the #1 injector line and see if you can feel a sort of a pulsation. TIA!

Normal, no isolator on line #1. Thats just the power you feel

 

Totally normal for the #1 injector line to pulse.

There have been several discussions on this but I can't recall the reason for the pulsing.

Yep mine does it too. Just #1.

 

Several thousand PSI surge causes it. Isolators do better job on balance of lines.
