that is what i meant.

take it off, and make sure you dont have a packing peanut in there, or a piece of plastic from manufacturing. (that has happened before)

also, you have a new pump with oils from production and new plastic that will need to be removed over a little bit of time.

if it continues for a little while, then put the old venturi from the old pump on. (its the same for the g2 and g3 (from what i have heard))

also, do you have a silencer on it, or a new hose? if a new hose, does it have a kink from shipping?
any restriction will make less air go through the pump , which in turn will pump lots more water....

if you have the old stuff, then i would put the old venturi and hose with no silencer on and see if it changes things. if so, then you know you have a air restriction and its just a matter of finding what its from.
