97prelude FPR same as 99Si FPR??????

[grand600]

Is this true or not? I had got a 97 prelude FPR to do the drilling to reduce idle fuel pressure. I drilled the reg w/a 1/16" drill and the idle pres did not change. The only difference I noticed is that when you shut the car off the fuel pres is 0psi as to before the hole was drilled it would take a 1/2 hour or so to bleed down. Does anybody have any opinions or how to on this subject. Thank you for the help

No they are not the same. The outlet size is different. The Si has a 1/4" outlet tube and the Lude has a 5/16" outlet tube. Also, if my memory suits: the Si has a straight outlet tube and the Lude has one that is bent 90' toward the drivers fender...

OK yes with those facts that are true...bigger outlet and hose bent the wrong way. Is it the same other than that? The question I am asking is... are the internals the same as a 99Si FPR? I don't car what direction or whatever. JRcivic is correct the hose ends are totally different. But does it function in the same way IE pressures and such??????
