DDECIV injectors, is it possible to only pull the solenoid?

Depending on which jakes you have. The ID tag is on top. The bolts are all the same length, except for 760, it has 3 slightly shorter bolts, they’re all marked with a circled J on top. Take note of the 2 spacer bars also. They’re marked “out”, I think they only will go one way, and one will read upside down, when properly installed. If only taking one Jake off, you shouldn’t ave to remove them. You’ll be taking the center Jake off for # 3, it bridges the 2 bars. The jake should be set on center, once the bolts are in and hand tight, since they can be slightly moved around. Except for # 760b and 765a, those should be moved as far forwards the cam as possible, before torqued.
