I'm replacing all 8 injectors in my 1987 F250 with the 6.9 Diesel. I broke a tip off one glow plug and not sure which one it is. I had 3 bad plugs so it's one of those I'm sure. Hopefully it'll blow out when I get ready to turn it over. Any suggestions on installing the new injectors? I've seen some suggestions in the past of what to do but nothing lately. Thanx in advance!!
