weeping/seeping injection pump fitting dilemna

L345DT TLB: Over the week I replaced the glow plugs (one was dead and the others SLOWWWW to heat and the forum indicated I should change the whole set), changed the fuel filter (nasty), air filter (filthy), and the oil and filter. The fourth glow plug necessitated removing the first two injector lines to get access to the glow plug.

After futzing around and finally getting all the air out of the lines I am up and running again. BUT, when I loosened number two line at the pump the entire number two injector pump assembly came loose before the line compression fitting came loose. I have reefed the fittings tight until I plumb scared that I'm going to really screw something up. Inspite of it all I still have a slight weeping/seeping of fuel from around the base of the injector assembly at the pump. Perhaps it is seeping down the compression fitting and only looks like it is at the threaded base??? But when I wipe it it sure looks like it is seeping up from the threads. What am I missing here? Is there some kind of sealant or teflon thread that can help? I searched the forum and have not come up with a good answer for my dilemna.

Okay, hopefully here is a picture of where the fuel is seeping from. Given the restrictions on image sizes you may have to Ctrl + to be able to read the writing.

After searching the internet, specifically tractorbynet and an diesel RV site, it appears that I most likely tweaked one of the pump injector O-ring, or two, when they came loose while trying to loosen the compression nut on the line. The O-rings are probably ancient and all it took was loosening the injector pump fitting to compromise their integrity. So, it looks like that will be my next adventure.

Whilst waiting for the head to arrive, I replaced the O rings and copper washers, or shims, on my L345DT injection pump that had the same leaking problem a thread on a leaking L245. ( http://www.orangetractortalks.com/forums/showthread.php?p=131983#post131983 )

Although the manual didn't show the O rings, they were there on the L345DT too.

What I am trying to run down is what torque spec to use for tightening the delivery valve holders?

I've spent way too much time googling, looking at manuals, and even emailed Oregon Fuel Injection (where I got my new injectors) without any success. All the manuals simply say nothing to service here without special tools and expertise and that is all.
