fuel pressure regulator o-ring size (I searched)

[dhen]

I bought a pack of o-rings and none of them fit the fuel rail. Does anyone know the correct size? I also tried 7X11X2mm and that was a little too small. Would 12mm do the trick?

Thanks,

Did you try lubing it up to get it in there? Even the factory ones can be stubborn unless make 'em all slippery-like.

Yeah, I feel foolish. I put some engine oil on on a 7/16X1/4X3/32 o-ring and slid in once I tightened the bolts. It was frustrating trying to find the right one, though.

Thanks,

Yea, you've always got to lube those o-rings. IDK how many times I've seen ppl not lube the o-rings on injectors when they replace them and then look surprised when it leaks.
