It ran fine without the lines hooked up? And if my gauge is reading zero back pressure That don't seem right? No back pressure would mean no work for the pump so hy would that be any different than it running fine with no diffussers I'm running a 300' run 190' and about 175 roughly?

I believe in catch and release. I catch then release to the grease..
