As far as I've ever seen, the high pressure lines are rigid tubing linking the pump to the fuel rails; typical for DI. These shouldn't be sensitive to low Hz vertical accelerations themselves; it could be that some other factor led to fuel vaporizing which then cascaded to a pump issue which led to a pressure spike damaging a line. If he means relatively high pressure as opposed to high in an absolute sense, then this might be a reference to the flexible hoses on the low pressure side; again suffering a fuel abnormality. Low Hz friction from porpoising acceleration I would not expect to damage a hose, and surely they are routed far away from any exhaust heat. Otherwise he's throwing chaffe as teams will be inclined to do.

Also, I'm getting confused between Craig's drawing and the actual RB rear end. The detail at the bottom looks completely different:
Craig is making the same assessment as Stu. However, if the torsion bars terminate as a pivot, they no longer act as corner springs, but as a component of the heave device. No anchor to chassis. We'd have to consider why. F.e. corner spring rate vs proposed function of this linking device. It also has a miniscule amount of travel as evidenced by the displacement sensor. Otherwise it's just an extension of the rocker without flexibilty.
