Problem with the Pump of the D2 System

[Pammsel]

Hello,

we just installed the D2 System into our Seat Leon Race-Car. Unfortunatly we got a problem with the waterpump. the watertank is fine and the intake hose is full of water. the pump is running, but there in no water at the other side of the pump. Of course, the pump is running all the time, because of the missing pressure in the supply hose of the nozzle.

i hope you understood what is the problem and could help.
