I have a 1977, 35 hp Evinrude, model 35752 that I've been working on. The gas line from the tank to the motor is very stiff, always has been. Since it's old, I'm going to replace it along with the primer bulb. Can I just get same-size neoprene gasline from the local auto parts store, or does it need to be some special type? The neoprene is much more flexible than the hard plastic-like line that came with the motor.
