Replacement injector rail O-rings?

[LarsD]

I was getting ready to hook my injector rails up last night and one O-ring on the return line tore. Does anybody know what size (I measured the grove @ 11/32nd's) for sure these should be, and if they need to be a special material?

Thanks

Disregard... you want rail o-rings, not injector o-rings.

They are viton o-rings, last time I needed some I bought a kit from Ford.

OK, I got a pack of assorted fuel safe O-rings in the "Help" section @ Oreillies. I was able to fish one out that was pretty dang close, the thickness of it was a little small (compared to the other factory O-ring that has been smashed inside the rails for 20 years), but it fit nice and tight.

I have a printed copy pf this chart on my desk at work. Has come in handy dozens of times in this particular situation
