Hi David.
I use the plastic injector fuel diffusers under the
injectors -but, there are many who do not. It appears that they are
designed to provide better atomization of the fuel by causing it to
breakup in the middle of the airstream rather than splashing against the
walls. They also provide some insulation between the injector and the hot
metal block. On the other hand they get brittle and easily break when
taking them out and they are NOT cheap if you have to purchase
them.
I have heard a number of reports that the stock Mazda
pulsation damper (located on fuel rail) has leaked in automobiles and even
resulted in fires. It appears not a question of IF but WHEN it will
leak. I have not heard a similar problem with the stock fuel pressure
regulator. About the only down side I can think of is that the stock
pressure regulator it is not adjustable - and that is not a problem if your
pumps are putting out the required pressure using one. I personally do not
use it.
Best Regards
Ed

Subject: [FlyRotary] 13B fuel inj.
deverters?
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.
