How much pressure does it take to press new fuel injectors with new o-rings into the fuel rail, not the intake. When i installed mine i sprayed a little WD-40 into the fuel rail to make things a little slick and the fuel injectors literally effortlessly poped into place on the rail. Does this seem right or should it take a lot more force? Could my o-rings be undersize? When i pick up the fuel rail with all 8 injectors and hold it up in the air all the injectors stay put and none of them fall out so they seem to be seated. Im just worried about leaks. :shrug:
 
before you start your car back up after installation, turn the key to the on postion a few times to build back up fuel pressure. while doing that, have some one stand by the motor to look for any posible leaks from the rail. if i remember, they just connect to the rail, not alot of force to put them in.
 
Yeah it doesn't take much to put them in there at all. I personally wouldn't have used wd40...but that would work.

When you bolt down the fuel rail it should hold them down if the injector o-rings are actually in...

flyinghi3 had a good test...
 
Yep, same for mine. I tapped the rails with a rubber mallet and everything seated nicely. That tip about turning the ignition on and watching for fuel is a good idea. I managed to ruin my first set of fuel rails and doing that helped me catch the problem while the car was still in the garage.
