Thx for the answer!You can buy any kind of tube and fittings you like to get the pipes shorter. I would switch to TPV or EPDM tubes and connections. For the pump you can switch to the DC-LT 2 pump.
I thought so!1. If you like to change the pump alone. But its a bit tricky.
2. Bit more expensive, but you dont need to change the pump, only this unit on the cooler. Bit more expensive, but easier for mounting.
I did that once again.Sounds like a micro-bubble in the pump to me. Shake the housing a bit, put it on its side or tilt it back a bit. It may help to loosen the bubble.
