I'm going to replace the o-ring on my fuel injectors. (I smell a raw fuel smell and the car's service record indicate it has had this problem before and that it was the injector o-rings)



But... where are they? Do I need to take off the intake manifold?



Thanks,

you need to take off the intake manifold. DO NOT DRIVE THE CAR!!!!!!!!!! there are a few recalls for fuel lines also you could have a bad fuel pulsation dampener!!!! if you are not 100% sure of what you are doing. i would suggest taking it to a rotary specialist.

KEEP A FIRE EXTINGUISHER IN YOUR CAR!!!



don't mean to be so worried but better safe than sorry....

 

yah if they already did the o rings is most likely the primary injectors and the pulsation damper.

You have to remove the intake manifold, solenoid rack, and all other rerlated hardware. I would recommend also replacing the fuel pulsation dampner, and the fuel lines as well. If you are mechanically incclined then this won't be too hard. If not, then take it to a reputable shop. Also, watch out for the metering oil pump lines, when removing the primary fuel rail.

 

My injector O rings failed pretty much instantly. One minute fine...next minute fuel pissing out onto the ground, dont take any chances with fuel bits.

 

It's a mission if it's your first time doing this. Be patient man and don't just pull on anything. So far everyone's advice is good.
