Couplings should all be supplier parts, for both hoses and tubes.
"blame porpoising" might be the go-to response by team personnel this season. So you get to answer the journalists without telling them anything, because few in the press fully understands porpoising yet.

Completely agree. It may easily be some resonance that is difficult to replicate/simulate because of the influence of temperature and the effect of porpoising, both very difficult to simulate.
Yet, at most the porpoising can only make the driver's head bob. If it affects a fuel lines, surely it would be on the low pressure side, or something in the tank (vertical sloshing). I can't see it having much influence on the contents of a 300 bar (or whatever pressure they're running now) pipe. Shaking an engine at low frequency seems like a non issue compare to all the other vibrations and impacts it sees.

Somehow it seems RB went adventurous in the design of the fuel system.
Fuel systems are pretty bang on standard these days. There is very little you can do.
There's the whole fuel tank though, that no one gets to look inside of. That's where my suspicion lay. Some flexible parts, baffles, who knows. An unusual gas used to pressurize the fuel tank having some ill effect. A moveable mass of fuel used to absorb porpoise acceleration. Or simply vertical sloshing starving a low pressure pump (although wouldn't this be a problem for other teams as well?) Then of course there's also the sabotage option. Maybe Helmut is speaking in code. "We have porpoises in our midst."
