Default Corvette P/R output adapter

On my Corvette pressure regulator, I am using Russell #644020 adapter for the output to the engine. The adapter will slip in but does not seem to lock up tight. I am wondering if I am using the wrong adapter!

I will use Russell #644120 thread on quick connect when I get the right push in adapter.

I am having same problem as AB6DO. I purchased regulator kit from Spedway http://www.speedwaymotors.com/LS1-Fu...Kit,41791.html

It has the Russell part number 640940, when I insert this part into outlet side of regulator it does lock, however I'm able to pull/push this line a bit maybe 1/4 inch. I'm thinking this will leak. Is this common or is it inferior part?

Thanks for responding 1964SS. It's still got me concerned, I'll proceed though.

I would not use those older style Russell connectors. There are several documented cases of them coming off and causing fires.

Russell makes a new style fitting that has a screw on rear lock. Those are excellent. Look for pictures and part numbers in my Cougar build thread. Link in sig.
