Hello,
I just put my throttle body back on just for the car to start spraying gas once I turn it on. Do I just gotta tighten the flange where it’s leaking from? I’m not sure what happened if I maybe disturbed the line while I was taking the throttle body out.
It's hard to tell from the video because the return line is sitting right over the top of the feed line that's leaking. However, it appears that the hard line portion of the feed line is cracked where it meets the flange that bolts to the fuel rail. If that's the case, your best bet will probably be to buy the aftermarket replacement that STM sells here, or see if someone has an oem one laying around they would sell.
I agree with MasterNater, I have nothing more to add really except a couple pictures.
Shot of frame where the gas starts spraying:
Maybe someone accidentally leaned into the hard line while working on the throttle body and cracked it here:
A crack there would spray upward like the video.
If there is no crack in the hard line then just tighten it and see what that gets you. There is an o-ring in there that should seal the pipe if it's been tightened properly.
