After completing a head gasket and injector job one on the bajo bolts on the HPFP leaked. I used the new viton coated steel washer throughout. Torqued to 18 ft-lbs. Should i lubricated the new washers when i replace? Is it common for new washers to fail?

I have run into this problem a few times. when you are using the new washers you have to replace the lines. Reason is because the old washers needed a higher amount of torque. This has distorted(warped the face) the banjo fitting, and the new washers cannot seal properly.
Replace the lines and sealing washers again. I have also run into where the fitting that screws into the pump will leak as well. Fuel can wick up around the fitting threads.
Pull the fitting out while you are there, clean the threads and apply a tiny amount of lock tight.

Yup exact thing happened to me. Copper washers originally on the line and was warped enough to easily see it. Didnt think to check before putting it back together but now i check all the lines first

Use the steel ones on the HPFP, the copper one tend to egg shape when torqued and then you get a wonderful leak that requires tearing it all apart again to fix.
