Yah you can make one. Take a 1/2" PVC T and stick it in some boiling water. You need to create an area of low pressure to suck in the air. After its boiled and softened up a bit, use something like pliers or even better a hose clamp right in the middle of the T. Clamp it down to create the smaller opening. Then hook an airline up to it, connect to your pump and viola! DIY venturi.
