Fuel Pressure Take Off Fittings

[roosduster]

Does anyone have any experience with these? I was thinking of giving one a try. The one I bought is http://www.summitracing.com/parts/RUS-670343/ and I bought a fuel pressure gauge and I figured they would screw together easily but after a few threads it seems to bind up. I did not want to force it so I stopped and unscrewed it. Is that normal and you have to force it or should it screw together easily? Thanks

Thanks, I will try that. Should I use any kind of sealer or will it not be needed with how tight it fits?
