that's a header tank/breather tank , it's not a swirl pot . there's no swirl , all 3 fittings are spraying at each other. it's not particularly efficient at its job honestly the way its built. and i love HPI, but this is a part to pass on. because of the lack of swirl and appropriately sized return , the water is turbulent inside and doesn't drain well or properly . . its under enough pressure to just keep the air moving and not allow it to centralize and surface . swirl makes that funnel effect allowing the air to go to center and bleed out through the rad cap , to overflow.
Just got one from gktech that’s pretty similar, Dan didn’t make a install video like he does with every other gktech part but this was spot on with what I was looking for much appreciated!
Tyler the hose that goes from the original radiator neck overflow tube nipple, and now goes to the swirl pot - is this hose now under pressure all the time I take it?
