Default H23/H22 help
What is the difference between the H23 fuel pressure regulator and the H22 one? Is there also a differnce in the size in throttle bodies in these two? make a difference?

I was wondering the same thing about the FPR...I'm using my h23a fpr only because the h22a fpr was hooked to some sort of vacuum solenoid and I didn't want to mess with it.

I would think there is a differance. The H23 fuel pressure is higher than the h22. I'm only speculating.

I am almost positive that the FPRs are different.
