Fuel line o-ring holding me up

I am restoring a 90 lx that had an engine compartment fire, and I am almost done with phase one, getting it running again. I have one problem that nobody seems to be able to help me with. When I disconnected the fuel lines from the fuel rails, I found that the o-rings had been damaged, too damaged to even have a reference for replacing them, and it seems as though none of the one I have tried fit right. So if anybody knows off hand what size o-rings go into the spring lock fittings between the fuel lines and the fuel rails, or if anyone is willing to check, I would greatly appreciate your help. Thanks

The lines should be okay, doesnt seem like the fire was too bad, just enough to mess up the o rings. The lines are steel, and dont seem to be harmed other than the o rings.
