2015 6.7 injector install need advice

[C-MAN]

Hello everyone! I'm getting ready to install injectors and connector tubes and I purchased a Mahle top end gasket kit to do the job. It came with the set of copper washers and O rings for the actual injectors themselves but there are no new connector tube O rings in the kit. I am installing the same injectors that came out of it and am wondering of I can reuse the connector tubes since they are pairing up with the same injector they were mated with? Also the copper washers the kit came with look identical on both sides from what im seeing. Does it matter which direction the copper washers go onto the nozzle? Thanks in advance

One thing some companies require is to use the new tubes, so you'll get the warranty with the new injectors.

At least that's how my process went with going with II.

I don't believe it matters what side to use for the washer, If I recall, they are the same.

Since you are keeping the tubes matched up to the same injectors you should be fine. I would carefully inspect the tube ends for any signs of damage and follow the installation procedure attached. I would torque the tube nuts a little tighter to a final 45 ft/lb because they have been previously crushed. The new copper crush washer can be installed either way.
