Fuel Line Cleaning
Any body cleaned their fuel lines just before completion? I'm thinking there might be dust in the lines because I've working on this for 10 years and now almost done seems like I should blow out the fuel lines before running fuel thru them and thru the filter and pump. My fuel lines are all hooked up from engine thru aux pump, filter and out to the wings. Wings are not on yet.
Can I blow from the firewall back thru the aux pump and filter and out the wing connections? Or is the pump/filter a stop so that I need to clean them from there in both directions? I'm assuming air will blow thru the valve one side at a time. Right? Will blowing air thru this break something? Perhaps better question is will blowing air thru the lines do any good?
