I just installed a raptor 100 pump, it is quiet at an idle and you dont hear it when your on it but at about 30 miles an hour there is a squeal and it stops when you slow down to 20 miles per hour and comes back as soon as you hit about 30 again, noise does not change with a rpm change, I pulled it out of gear and it did not change, it is like flipping a switch soon as you hit about 20 it stops and comes back on about 30. any help would be great.

i would bet it is sucking air. (loose connection at the tank) I would call pureflow.

So what would be the best way to check for sucking air, I just installed my pressure gauge, and it seems to be little erratic and moves around from 14 to 18 psi when running about 30 mph, is this normal? it only moves a little at idle, I currently do not have my smart installed and it pulls down to about 10 to 11 psi when you get on it, is this normal as well? any help would be great.

I would reset the connection on the top of the tank, I know it is a pain, but when connected you should hear a "click"

I did not mention that I installed a MK-2 at the same time, purged everything to flush out the lines really well, but I am now being told that I may have three injectors going bad, they tested out between 91% to 100 for two of them anf one is running at 105% to 110%, we are now waiting for them to get in 6 new ones before we pull them to test but there is about a two month back log.
