The only distance that matters to the pump as far how much air it can push is how deep underwater the airstone is, which you said was 17 inches.
Water adds 14.7psi per 33 feet. So 17 inches is around 0.67psi minimum needed to blow air. So basically any good air pump will do.
One thing that came to mind when you said where you're putting the pump, have a stop-vavle (one way valve) so if your pumps shuts off for any reason the hose won't accidently siphon water into your airpump.
