Fuel Lines & pipes to Rail Bolt Torque Spec's

[ellishedderly]

I am replacing the injectors, & had to remove the plenum and injectors. But neither of the three service manuals give the torque for the bolts to the fuel lines (intake & return) or the bolts on the fuel rails, I loosened to change injectors.

Also, since I loosened the bolts on the fuel rails, should I replace the "o" ring for the fuel pipes?

Thank you,
Ellis
