Before I make a big mistake, I just wanted to confirm with the experts if it's necessary to have FI rated lines on the intake side of the fuel pump (between tank and pump) for an SE.

Thanks

Not on the inlet, though it might be a good idea since it's supposed to be neoprene and can last a lot longer before it degrades compared to rubber. Can you find high quality fuel injection hose in 1/2" that is required on the inlet side of an SE pump?
