i have been using the KAS fuel line for refueling from my mining base on minmus and i haven't had a problem with using it to fuel the problem i have had though is struts dont seem to be working, i have 3 empty jumbos with empty rcs fuel docked in a line with a tug and it is as much of a wet noodle with 8 struts between each section as with out them, they should be stronger than that yeah?
