I used to use a JROCPRODUCT fuel transfer pump, it pumped 9 Lt min and had a cutoff switch just like a fuel bouser. I used it for couple of years and it was great, but I didn't like putting 20 Lt jerry cans on my Jabiru wing. So I came up with another refueling system, I mounted a 90 gallon an hour Hollie fuel pump on my firewall connected to a 4-pin plug mounted on left hand side of my dash and then connected back to the battery, I have a 2 m length of 4 wire cable with an ON/OFF switch at one end and the other end plugs into the 4-pin plug, I have 2 quick connect fittings at the bottom of my firewall that go to the IN and OUT on the Hollie fuel pump , I then have two lengths of 12mm clear hose with quick connect fittings, one hose is a meter long and goes from my 20 Lt jerry can near my nose wheel to the IN quick connect on the Hollie pump, the OUT hose is 3m long and I can reach both fuel tank. I can put my Mr. Funnel in my wing tank, put the hose into the bottom of the funnel and it stays there, I turn on the switch and it takes 5 minutes to pump 20 Lt.
Works a treat.
