Z20LET Fuel Rail into Z22SE - LMF Regulator

SpaceWalker

Hi Fellas,

I bought adjustable fuel pressure regulator from LMF.
Tried to install it, but have some problems, is not fitting properly as the inner core and the beak of Z22SE are slightly thicker than the LMF/Z20LET one.
Also the regulator is mounted with 2 bolts, not like Z20LET with cramp.
If anyone mounted such, could you give me some advises what is needed to have it properly fitted?
What is the stock fuel pressure of Z22SE so to know how much pressure to apply?

Cheers Folks!

Can somebody tell me the stock fuel pressure of Z22SE (3 or 4 bars)?

Thanks fellas!

z22se is 4 Bar standard

SpaceWalker

Thank you vocky, much appreciated.
Will install the adjustable fuel pressure regulator today and wanted to know what pressure to apply.

3.8 - 4.0 Bar is average fuel pressure for the z22se :thumbup:

I think 4.5bar will be more than sufficient for me 🙂
As i am trying to reach 13.0 AFR for Open Loop, as we know that the std map is 14.7.
