Are they simple enough to do solo first time? I'd like to do the work..as long as I don't destroy them in the process
Yes they are easy. Pull injectors, place in vise, remove nozzle and needle, MAIN PART DO NOT LOSE PUCK!!! VERY SMALL!!) when pulling needle and nozzle off body do it slowly and make sure you don't lose that puck, other than that keep a clean area, when reinstalling torque to 55 pounds. The end
