HFS-4 pump vibrating

[rideekulous]

I’ve got an HFS-4 kit with the Howerton twin tank. My car has been down for the better part of a year for engine rebuilds and many other changes.

I actually had it on the road for about a month; I was getting ready to tune so I was testing the Aquamist kit and ran into an issue with a diode on the controller board that Richard (Aquamist) helped me sort out... thanks again for that!

Right now, the only outstanding thing is that the pump is vibrating and is quite loud. I connected a 6” hose to the outlet of the pump and cycle it for a while, here are a few videos to show the symptom.

Video 1: Controller jumped to SYS.
Video 2: Controller jumped to SYS, after cycling for about 4 minutes.
Video 3: Controller jumped to SYS & FAV.

In all the pump was cycled for about 5-6 minutes and the vibrating persisted. The last time the car was running with the injection tuned in, it would only make a hissing sound when spraying... so the vibration is concerning me. Getting the car ready to fire again this week, I would appreciate any assistance.

It was suggested from my local distributor/vendor, Howerton Engineering, to "remove the pump from the unit and turn while running, outlet up, to get all the air out"; is this OK to do?
