I am also interested as I get started into jets. I have read that Evo jet makes a fueling station with a variable flow rate, or you can use lower voltages, some even fill at a high rate and switch to a low rate for the satellite tanks. So I gather that you can damage your tanks or introduce unwanted air into the system if you fill at too high a rate. The Evo jet is not available in the states right now, or I haven't found it. I would ideally like to start with a variable rate pump.
