🔌 Edelbrock 644113 EFI Adapter Fitting: -6 AN Male to 5/16" SAE Quick Disconnect Female Screw Type - Black Anodized Finish Review

Works great. I feel better with it than the plastic clip version. They have a positive latch for less chance of fuel leaks.

Upgrading the fuel line in the engine compartment is now easier than expected. The end result is clear, leak-free and precise fuel control. About $600 for additional hardware lol, but it's definitely a nice upgrade.

These are ideal for connecting a flexible fuel sensor to the 6AN return hose. The circlip is ideal to protect the connection from the very high fuel pressures generated by racing cars. To be on the safe side, I recommend a *dot* of blue Loctite. But other than that, it makes a pretty reliable impression.

They are great and don't come loose like the ones held by plastic. I had the same fitting but with a non-threaded plastic insert on the end. It's 100 times better, they don't come loose and no plastic thing known as a padlock lasts very long. Trust me on that. Now I have two on my car from -6an to 3/8 and life is great.
