AN fittings?

[CamaroChris]

OK guy's, I know I have been making a lot of threads lately And I hope it's ok so far. I love this forum and all the info here. But I new question I have is about AN fittings. Here is some nicly priced ones I have found, http://www.anfittingsdirect.com/inde...99ac891b2107d5 while reading through there info, this company talks a lot about one brand of fitting not matching up with other brands and they also say that their fitting will only work with their stainless "Teflon" hose. Anyone hear this before or used this brand? where else sells fittings at a good price? This company that i posted says that the stainless braided rubber lets out gas fumes? that does not sound right ? or will it. I just wanna buy some stuff that will last 20 more years. I need fittings for my trans cooler, fuel system, and hydroboost. also how do I flare the stock fuel lines to adapt to -4 and-6 AN fittings? I have seen compression fittings but they say max psi at like 30psi and my fuel pump is 90 psi max
