I'm talking about both hose connections. Not sure what they do, but one has a big diameter (radiator hose size) and the other is pretty itty bitty (vacuum hose small).
I used screwable type hose clamps for both hoses instead of the stock hose clamps, because the stock hose clamps would clamp, but you could still easily remove the hoses by tugging on them, which tell me that they would leak under pressure.
Now that I use the screwable hose clamps, they don't move, thus a change of sound. IDK, maybe its just me. I'll try to video and post it, hopefully the audio turns out.
Maybe I'm the only dumb one that didn't think about changing the clamps to something that secured better??
