[Z06vette]

I've had issues with the blue fittings shown above not locking in. This was the older style however. In one of my car mags I saw there is another style that has a clip that goes over both ends of the connection, similar to the clip GM uses on the hose/fuel rail connection. Let us know how you make out with the new fittings. My guess is that its the fitting & not the regulator, but you never know these days
