Yep that is one way of doing it. One of the most common ways infact, but I dont like it. The method Im looking at doing removes the need to do like you say and switch to diesel to remove air. Also I am not using a 6 port valve. I have 4 fuel tanks and buying enough 6 port valves etc. is crazy. Also if Im in the middle of South America or OZ (ok so Im sorta dreaming) and a electrical problem kills the 6port valves Im in a world of hurt. The previous owner of my Mog; who traversed the Saraha and Siberian deserts, and Iceland in this truck, hince so many tanks, already had 4 manuel valves installed for swithcing from tank to tank with the return only going to one of the tanks. I'm using this same format with my system.

If you want to get totaly confused here is a link to what Im doing.
