Im thinking this may have safety issues attached, EG draw/fill up with cold fuel from the tanks at Birdsville
then go inside and have a session on the beer, you'd have fuel dripping everywhere IMO.
Im leaving mine STD if I want 20ltrs Ill fill a jerry can, sorry but thats just me.
OOI what if something happens in an accident and it catches fire the insurance will see your fuel lines all
re arrange , Nah sorry again, not enough Pros and too many Cons
