Help Please - Fuel leak at the end of fuel rail

As i was driving I smelled fuel after installing a 3 point strut bar.
I believe I hit something in the end of the fuel rail. I can't describe it cause I don't have a digram and the books I have don't show it.

does anyone have a good pic of the back of the fuel rails>

also a step by step on how to fix it.

thank you so much in advance.

Is the leak toward the back or front could be fuel pressure regulator or fuel line hookups try to be more precise.

Check the schrader valve on the back of your fuel rail at the very back of the intake. It is a screw port with a cap (if you still have the cap) as these are notorious for cracking that the base due to weak welds. Just turn the key to the on position (priming the fuel pump) and feel the back at the base of this valve and also feel to your right where the fuel pressure regulator is and you should be able to find it as it will be spraying or dripping. Doubtful it's anything up front as you would see it. Look at the below exploded view from Shoe Box's website as the scrader valve is listed as 7,8 in the diagram:
