fuel pressure regulators

[jessica]

Need information on two specific fuel regulators,

Z22SE fuel regulator without vacuum tube,
And the Fuel redulator of the Corsa Vxr A16LEH

What pressure Each of them ?
I think but not sure the 2.2 is 3.8 bar
And abot the 1.6 corsa VXR I can't find any info in the Web.

A163LER has 3.3 bar I think and z22se has 3.7-4 bar

3.3 and 3.7 bar, Interesting

the z22se built in a different way, there is no vacuum Tube on the regulator valve
It's supposed to be critical?

and I have another question, If I'm not bothering..
the Regulator - maximum point on 3.7 bar - and 3.4 consistently runing Normally
or Permanently or 3.7 without Reduce the pressure change?

The 2,2 does use a vacuum it's when it's at low revs it runs much more economical and then at full throttle or at a certain rpm it uses the full 3.7 bar

I don't really understand the question but the pressure isn't adjustable if that's what your asking, you can buy aftermarket adjustable regulators but the standard ones just run constant bar, apart from the 2.2 as mentioned
