IMO< YES....as long as it's properly clamped FI hose and clamps, I use hose rated for FI to 250 psi and it's stamped in RED....I think that mechanical connection is going to lead to something breaking, mainly the pump plastic end there....with vibration, I don't like it at all...
under the engine compartment from the stock lines to the engine and from rail to regulator, I used black cloth covered braided steel reinforced Aeroquip hose....found the rubber tended to pulse too much, then the injector batches fired when grabbed I could feel it, and figgered too much oddball pressure problems contributed to irregular idle, and so that helped a LOT....
