Injector oring leaking Please Help!!

I have a 2001 ford f150 4.2. I replaced the upper and lower plenum gaskets to fix other issues and codes i was getting.Also replaced fuel injectors since i was right there and figured it would be best.Everything is together runs great no codes but i have an injector leaking fuel .1 i can smell it around the cab and 2. i can see it puddle up around it.Ive since went back in and replaced the orings on that 1 leaking injector but it still leaks.Can someone please help me out here...TIA

I would pull that injector and make sure it is not cracked or damaged... if you have installed the o-ring twice and it still leaks.. look deeper.

Make sure you didnít leave an extra oringbin either the manifold or the fuel rail, keeping it from fully seating.
