FIC Injector question

[Quasimondo]

I just installed a set of FIC 650 injectors, and they don't seem to be seating right. I can hear air leaking around the lower head seals (sounds like a pressure cooker when it's at full boil). Has anyone had this same problem when they installed FIC injectors? Am I missing something here?

This is the right seal, correct?

They sale different seals for different injectors.

Problem solved. I had to remove the spacers that went between the fuel rail and the manifold. I just replaced them with washers that I used as shims until it was seated nice and good. Good thing I bought a set of rings and seals before I installed everything.

That's good, I will be doing mine soon hope I won't run into problems.

are you sure that was a good idea not using those black spacers? Those things are there for safety purposes and so that you don't overtighten the bolts connecting the rail to the head. Ive read here about someone who didnt use them and his fuel rail snapped in half. Just thought id bring it up just in case.

I always use oem injector orings for FIC injectors, they are a bit of a pain in the ass to get them to seal good, but I'd much rather do that than remove the black spacers.

Get a new set of oem o-rings, and put the black spacers back in, very caregully guide the rail and injectors into their seats, and you will be fine, remember over tightening can tear the seals, so can tightening it down without the injectors properly seated

The noise you heard may very well have been a torn seal, when it comes to fuel dont mess around, pull the rail and check the seals, if you have a torn one you can blow fuel out under boost.. call me crazy, but that sounds like a bad idea
