Successfully removed engine - injectors sprayed gas??

[Steelepuls]

Hello all, been a while since I've been here. I don't want to hijack this thread, but I need help with an injector clip question.

I replaced the AOS hose that starts at the AOS all the way to the far side of the engine (front driver side connection). This project started out just replacing the vacuum lines and vacuum canister. Boy, did this balloon up to a bigger project. In doing so I had to take the intake manifold off and the injector rails.

While reassembling the fuel rail, the #4 injector clip was lost in the engine bay unfortunately. I looked for couple hours with a magnet and flashlight, had no luck. So frustrating.

I ordered the clip to replace it, but my impatience got the best of me, and I could not wait for the part to arrive, so everything was re-assembled, it started up fine, no leaks on the #4 injector, the car ran very smooth. After starting the car, the vibration shook the clip loose and I found it on the ground the next day.

My problem now, is the #4 injector is way too cramp for me to install the clip again, without disassembling the fuel rail again. I need some advice, there is a bolt to hold the fuel rail down, and it is right next to the #4 injector. Does the clip have a critical job or is it just to hold the injector to the rail during disassembly? Should I take the fuel rail apart again? or can I run it for a while without any issues? LMK your thoughts please.
