I have just recently replaced the o-rings on my injectors and it is leaking again on cylinder 4 from the top of the injector. I have an STR fuel rail and stock injectors but dont know if thats a factor. I also have b&m fuel pressure gauge anf the needle recently wrapped all the way around for some reason but i am sure that the fuel pressure is close to stock??? Any idea on why these problems are happening would be great. TIA

 

Bump ppl i need some help or advice on this one

 

weird.. i just had the same problem with the exact same set up... fuel leaking around the #4 injector with stock injectors, str rail, b&m fpr.. i just installed new o rings on all the injectors and ran it for a little while and no more leak. we'll see what happens after a couple days of driving though.

 

Ya ive had my new o-rings for about 3-4 months and it was all fine untill i started to smell gas today and was like wtf??. Sure enough i popped my hood and saw gas seeping down from cyl 4, everything seems to be fine but ill probably just take it apart and put new rings on it and see how it does.

 

any luck fixing the problem??? looks like the leak is back for me only thing i can think of is the intake mani gasket..

 

I have the same thing. I wonder how deep the injector should sit?
