P1 Fuel Injector Leak

P1 Fuel Injector Leak
1988 FC S4 N/A
Just did ratsnest removal and put everything back together to find i had a leak on primary fuel rail. So I sent my injectors to KGParts.com who did a awesome job.....but no......it still leaks. my injectors used to suck BTW lol
Last night after recieving my injectors i put everthing together except uim. Primed fuel and no leaks YAY!!! So morning came went to start her up or try to. So after no starts and start but die I decide to look around just to make sure everything was pluged in and there it was a puddle on the front rotor housing.
Last night prime system no leaks, morning startup leaks, morning prime after UIM removal and primary rail removeal with injector switch, then a 8 min prime leaks 5 min after i turned off the pump. It leaks from P1 injector (Primary Front Rotor) . P2 is perfect and used to be the P1. I did find its leaking upwards from block up only on P1........
What would cause this? Im thinking particles or something but i cant find any.
Im so tired of taking off My UIM i want to push her off a cliff and set her on fire.............but I wont....... ever...........

What does fuel injector cleaning have anything to do with the fuel injectors leaking EXTERNALLY!??!?!
Godamn it people, use some common sense here...
If it's leaking fuel externally, CHANGE THE O-RING.

the fuel injector is not leaking. The injectors havebeen fully serviced everything has been replaced including O-RINGS. the problem is fuel is comming up from the block where the injector goes into the motor i dont think its injector itself. it comes from the hole in the block where the injector fits in.

ok everything on the injectors have tested and have been replaced everything. The problem isnt the injectors no matter wich injector goes in the P1 hole it leaks. but the injectors do not leak in the other injector holes.
I even have the test results showing the injectors do NOT leak.

Your someone so respected why be disrespectful?
KGParts.com is who serviced my injectors. This is a quote from there ~*~Fuel Injector Cleaning Special for RX7Club Members~*~ Thread

You're right - if the fuel injectors were recently serviced, if there was something wrong with them, they would've been rejected by the test.
Why would the fuel injector be leaking from the bottom?
Explain to me how that would be possible, especially if we're talking about an engine running in vacuum like at idle?
Just because the o-ring was replaced doesn't mean it's still good.
I've "nicked" o-rings on the install, which caused fuel to leak all over the fuel injector on "brand new o-rings".

Do you have the plastic spacer that goes between the injectors and block?
If it's not there, the injectors won't sit right. I'm 99% sure this was my problem when I had a leak.

Yes i did check the air bleeds i thought it would be that, but cleaned checked for tears and nicks then oiled the airbleeds and cleaned out the hole replaced and seems fine.
When I first installed the injectors I lubricated the o-rings as per the FSM.
Yes i have the spacer, I actually have a couple of them.
One time i forgot to put it in about a year ago an ran the car so i could go get more things from the auto parts stotre but it never leaked.
After redoing the system this afternoon and cleaning all the holes lubbing the orings everything checked for tears everything and found nothing for the 8th time .
I primed the system for ten minutes and turned it off to wait to see if fuel leaked. and it did not. I am hopeing that my problem has been fixed .
I really appreiate all of your help guys. Thank You

Which means...the engine has to run first.
If there is a good sized leak, the pressurized intake can possibly "push" the fuel back up through the hole, where it's only atmospheric pressure - i.e. lower than the pressurized intake.
