Good question - i guess there could be simply installation error. Some couplings are pesky and unpredictable. From mine experience. Handling some sort quick disconnect could became quite a quick oversight if u are changing a lot of parts in a hurry.PlatinumZealot wrote: ↑22 Apr 2022, 04:03Anyone know what sort of couplings they use on the hard fuel lines?
EDIT: Not that hard to mess up threaded one also. Some tight space in those F1 cars and even harder access of the tools. In this case. I imagine you can quite quickly cross thread connector also.
