After some deliberation I settled on the exact pump I wanted and also how I wanted to transfer fuel from the long range tanks to the main tanks. I am deviating from the plans but it does not make sense to me to bring the fuel from the LR tanks into the fusalage center console to redirect it back out to the mains. Its more complexity, material and valves. I also opted to not use the provided rubber fuel lines which need to be changed every five years and I am fabricating metal fuel lines which will be good for life.
