Review on TASAN RACING Valve Fitting 8AN 8AN by Alex Tilden

I bought two of these from another seller and both have leaked. I then bought this one, hoping it might have been from another vendor's supplier. nope This one leaked just like the other two I bought. It was fine when I first put it on, but when I checked about a week later it was leaking fuel. Maybe they're just not designed for gas. If it's an important part that doesn't need fuel to get through I'd spend the money and buy a good block at a speed shop.
