Stick with oem. Regardless of the fuel compatibility problems (which are a big deal), any of the colored stuff (and I would bet the tygon too) will take a set over time. That means the ziptie is the only thing sealing, and not the fitting barb. Several times I've found fuel leaks in my ski due to vapor pressure causing blow-by leaks at the fuel filter barb.
I just ripped the colored lines out of my skis after only 2 years, and put in autozone black fuel line. Not sure if that's any better, but I was in a hurry. Next time will be used oem line for sure.
