search is down so ill have to post here well to start off Ive been experiencing some rich conditions part throttle. Just got around to checking fuel pressure. Well my readings were 32psi with vac connected and 42 w/out vac im using the old h23 fpr and i see that the h23 fuel pressure is alot higher than the h22 so is the h22 fpr different then the h23?

just for reference the manual says i should have 33-40 w/out vac and 24-31 w/vac

 

well looking on SLhonda the part numbers are def. different... can someone with experience please chime in

 

Yes they look identical but are set at different fuel pressures. I was going over the fuel pressure specifications in the factory service manual and noticed that. So I made sure to swap the FPR from the JDM H22 fuel rail to the H23 rail I plan to use.

yeha i woulda used the jdm one but the return was angled different because it was on the other end of the fuel rail. so i just put the whole h23 fuel rail system on ...

so now i need a h22 fpr the usdm not JDM

 

Thats what I meant, I had to use my H23 fuel rail because of the JDM fuel line placement. I just unbolted the regulator from the JDM fuel rail and bolted it on to the H23 rail.
