Why can't i siphon the fuel out of the tank with a hose like we used to do Is there some sort of a. The previous owner was running it off the auxiliary tank only, as the main tank behind the seat was full of really bad gas I recently put a new main tank behind the seat Duel tank, both fuel pumps work but when pulling fuel from rear tank it also fills up front tank If front tank is full it.
When replacing the tank heater, i did break off the outlet line nipple, but thought i repaired it, so that might account for the reductant pressure being too low Anyway, my main concern right now is how much damage i'm doing if i'm not getting enough def into the vehicle.
