Fuel Rail O Rings

[32valvZ]

Are the ones inside the fuel rail, (there are 4) the same as the rest? I got Jerrys O ring kit and have 4 that I cant see where else they go...other than inside the fuel rails...

Since you have a 90’ you should have the 2 different sizes for the injectors themselves. 8 larger for the Primary Injector lowers that mount into the injector housing itself. 24 smaller for the 16 upper of all injectors and 8 lower for the secondary injectors. Then a smaller set of 2 for the fuel line to the fuel rail connection. These last ones are also used for the pipes, rails and regulator connections. That’s probably what your seeing.

So Phil rebuilt my FPR... I had Jerry send me a FPR O ring kit... this is not for injectors.... only the lines that go to the FPR.... Theyre all the same size. Inside the actual fuel rails, there are O rings... I wasnt sure if theyre the same as the ones where the lines plug into the FPR. I have 4 left and there are 4 bores, 2 in each rail that have O rings inside them...

Yes, I believe all the fuel rail o-rings are the same size. I believe there are 9 total O-rings for the rail/regulator.

I was skeeered to pluck them out of the rail with a pick and ruin them if they were different...
