Most members here at CC have NOT. They're posers like me.

So, our experience, or lack thereof, is skewed towards non-racing applications. The people at Hall Fab & Racing (i.e., racers) made the same suggestion to me, replace the crappy hose. So, I ditched what Kirkham gave me back in 2007.

You said yourself. "Is it better to have a silicone hose that is heat resistant? Sure."

Some people think two roll bars make their Cobra safer, but then, forget an inertia switch for the fuel pump, to turn the pump off, when the car flips over. It's all a matter safety and tolerance.

Not crapping on you or Morris' advice. Just that I am not aware of any fires on an SPF with the plastic hose including a Mark III that ran the "One Lap of America" with the standard setup. Is silicone better? Sure but consider what the purchaser wants to do with his car. He will not be running long open track events and driving 10/10s. Autocrossing is unlikely to generate the heat levels needed to radiate enough heat to melt the hose. Obviously the photo is of a serious track beast judging by the rotor and the double cooling hoses.

The advice IS appreciated however some people work on the "I did it to my car so you MUST do it to yours" or "I bought the XYZ sway bar kit and now I can go around the I370 off-ramps at warp speed" without considering what the owner is looking for.

And no inertia switch required with a mechanical fuel pump however a check valve in the tank vent line is always a good idea to prevent hi-test baths.
