leaking injectors

[decavo]

After I installed the fuel rail the injectors are leaking I only replaced one of them. that one is not leaking. I replaced the Orings with new ones, only #3 and #4 are leaking. Any helpful hints as to how to remedy this situation?

You replaced one injector and put new O rings on it? And now the others are leaking? Take it apart again and put new O rings in...

put new o rings in all of them... 3 and 4 are leaking.. replace o rings many times today.. still having issues... I picked up some more o ring at the zone going to try again in the AM

 

[decavo]

is there a technique to installing the o rings that would keep me from pinching them?

I lube them up with engine oil when I install them, that's about the only trick I know...

I believe the FSM says you are supposed to pre-lube them with gasoline.

Where are they leaking?

Ditto that one, I always just put a little 30 weight on my finger and grab the o-ring and it'll slide right on w/o pinching, nicking, or tearing it.

x2 on the fuel....though oil should work just fine also.

 

[decavo]

they are leaking at the fuel rail... the inlet side of the injector

replace the seats along with the o-rings again

be gentle

 

[decavo]

the seats are attached to the injectors nothing there is removable....

try to clean your fuel rail. I had a similar issue when building my friends 4runner. I ended up getting some aftermarket o-rings and i cleaned the hole in the rail with a pipe cleaner and it has not leaked since. we went through 2 or 3 orings on number 4 before that.
