I can see this happening if I observe the pump operating and then switching off. The pump does not act as a check valve but I wondered if the Aquamist check valve would solve the problem - it would be doing the reverse of what it's intended for (stopping siphoning through the pump when the jet is mounted after the throttle body).

Thanks, Huw.
