hello need advice, my obs idi just shut down on me and i did the process of elimination and i thought i had it narrowed down to the lift pump, so i replaced the pump and i am not getting any fuel to the pump from either tanks, is it possible that i have bad sending units in both tanks that went bad at the same time?? i think its odd that nither tank will produce fuel. Can i use compressed air to blow out lines from the lift pump line to the tanks or will this cause dammage to the slector switch for the duel tanks. all advice will be greatly appreciated
