Looking for info on fuel inj. deverters used under each injector by Mazda, are we reusing  or removing?   Am finishing last retainer brackets for secondary fuel rail.  Is the Mazda fuel pres. reg. being used or upgraded?   Is on ready to go but, I thought I read some where , they were not up to the task or borderline accurate?  Thanks,  David,  RV6A Rotary.
