Today I manufactured & installed the hoses for the fuel flow transmitter, They are stainless steel braided, PTFE (Teflon) rated to 260°C with stainless steel hose ends. In fact all the fittings after the pumps are stainless steel. I needed to re-drill the transmitter mount as the angle of the tube to which it is clamped, made the outlet side low which is undesirable.
