CUTLASS Close Call - AN fitting failed

[nycutlass]

In the world of drag racing there are very few "Safe" shortcuts, you are very lucky, I'm sincerely happy 😊 that your car didn't burn to the ground.
Brakes and fuel, in my opinion are two of the most important things you should pay attention to that tend to get shortcutted because of the difficulty in doing it right. When it comes to quick connect/disconnect, just say no. My two cents.

i personally feel how i wired my fuel pumps saved my car and maybe me in fact. I didn't put the pumps key on key off i wired the pumps to operate with the computer and let it trigger the pumps and i feel that was the key.

I avoid the ones with the plastic clips at all cost. These are the ones you want to go with. plenty have ran pretty high HP builds with this style.

Not sure what ECU the op was using, but putting safeties into either the software or hardware for the fuel system is always a good idea. I’ve learned to use them after having fuel issues several times.

If you install a safety, check that it works as designed as well. Saying that from experience. Using aftermarket ECU’s I’ve taken advice from others and have all of my safeties cut dwell time which essentially turns off the coils which in turn shuts off the fuel pumps. They can be a pita to setup and/or install, but they can save your bacon.

I think I had the same fitting fail, was actually just turning the key to unlock the wheel to turn it and move the Blazer around. Haven't got further into it but think it was the same thing, may look at that other fitting to see if that will be a better solution

You said that you ran a #8 line? The factory fuel rail is #6. If you didn't use the correct quick connect that adapts a 1/2" line to a 3/8 fuel rail, it will snap on the rail but it will be very loose and it will blow off.
