I guess you do like to argue. Any way you look at it, your story changes. You went from never use rubber, to the factory never used rubber, to rubber was only used if it was specially made. You also stated that rubber was never used in any factory application. There are plenty of cars where rubber was used from the factory. Some used compression crimp fittings, some used a barb and clamp. Various cars have different pressures for fuel injection. There are some injection systems which rate the pressure at 9-11Psi and its good. There are some carb applications where you want 40 Psi. It doesn't matter if it is injected or not. Pressure is what matters. If a barb and clamp is good enough for the factory, why would it not be good enough for a repair? Some cars even have the same tank and piping to the engine but a different injector system and regulator, resulting in different fuel pressures. Fact is rubber can be specifically made for just about any application. Use the proper rubber and connector and it will be good. Just look to your brake hoses for an example. How many hundreds, or even thousands of pounds of pressure are they rated for? Point is, as already said, I would have replaced the lines. But, there are alternatives. People on this forum are looking for help and guidance. Different ideas. They do not want a "militant stance" on your opinion, they want multiple opinions. You not only put your opinion up, but you went as far as calling out other members and stating that one offered "Horrible advise". Most people were in agreement with your opinion, but suggested alternatives may be possible, but you want to jump in and say your way is it only possible way. That's not what these forums are about, and this has strayed way off course from the OP's question.
Also, you suggest a leaking line causing a fire? Not sure if you missed this, but his line IS leaking already. With the factory lines. And he is looking for options to stop the leak. Call the FD and have them impound the car? Sounds more like a local ordinance to me then a federal law. But I am sure you took that into consideration when you posted. You know, about him being in New Jersey and you being in Ontario. I am sure the laws are not 100% the same.
Again, NO ONE said anything negative about repairing the line with factory equipment, The idea was even supported. The only thing suggested was another alternative.
And then, the price? In my area it would be about 1/2 price to use rubber. I still wouldn't, but it would be less expensive.
