|Do you have evidence to back up your findings that you can present and share?
Surely you can understand why people are cautious when it comes to something as critical as the fuel system - and even more so given all the redrills, counterfeit Nismo and other shenanigans. The easiest way to avoid all that mess is to buy a genuine product from a trusted vendor.
Trust isn't given openly - it must be earned.
I think you'll find a lot of folks would be open to a more reasonably priced, quality alternative to Nismos (raises hand since I'm in the market), but parachuting in, dropping your opinions with nothing to back it up isn't going to get more people on board.
Facts aren't facts unless there's evidence to back it up. Otherwise they're just "alternative facts".
