hi i just fitted a aaz to my truck just wondering is the old jx engines injetors the same as the aaz as i have a set of new ones will fit them if thay will work

No they're different breaking pressures, plus the AAZ are two-stage and taller. With the JX injectors and appropriate lines, the engine would run but with reduced performance.

Hi, what pump are you running AAZ or JX ?,you can run single stage or two stage injectors no problem with ethier pump, but the cam plates on the AAZ are set up accordingly for two stage, my injector guy prefers the single stage for power, but the two stage are deffently quieter and seem to give more top end power, with single stage in my experience offering more low end power. Its a bit of a grey area really, but if you have a new set of JX injectors over a worn out set of AAZ injectors its pretty obvious what your best choice is, obviously as Andy says the AAZ fuel lines are not compatible with JX injectors
