The 1.5 to 3.0 is the flow rate in the RPM range from idle to around 3500 which is cruise RPM. So if that you are in that range when testing from idle and when revving up the engine you should be fine.
Looks like its still doing what it should be doing...Thanks!...
I was just concerned when I got a Reading around... 0.5 to 0.8 @ Idle, then @ about 3000 rpms... it jumps to 2.5 to 3.0 and higher as the rpms go's up!
Thought maybe I was going to be installing a Electric Pump?...NOPE!!
Gunna just leave it alone...If its Not Broke-Don't Fix It!!...
