I pulled my injectors last night and had new nozzles installed this morning. Before I go to slap em back in. I just wanted to make sure that I had to the torque specs on the hold downs. If anybody knows I would greatly appreciate it. Thanks

Called a gm diesel tech (one of my customers) and he said just tighten them down to what "feels tight, but not too tight". Kinda scares me a little, but does that sound ok?

Install the fuel injector bracket bolts. Tighten the bolts to 30 N.m (22 lb ft)

Thanks man. I ended up installing them last night and could only find the specs on an lb7 (37 ft/lb). I knew they're totally different so i decided to go with 30 ft/lb. It felt snug, so I went ahead with it. Anybody think I should back them off?

Thanks again for the reply.
