whats the stock fuel pressure for a jdm h22a. thanks

 

can't remember if its 32 or 40 psi. Depends if the FPR is connected to manifold vacuum or not for calibration! For an h22 I believe its a tad higher than h23 so I would go with around 40 with the vacuum line connected. Some one else here will let you know for certain though hopefully. I'm only approximating and going of memory

 

30-35 psi

 

With vacuum hose connected (24-31 psi).
With vacuum hose disconnected (33-40 psi).

 

ah (oopsy)
thanks, my memory needed refreashing
