i have a 1997 integra gsr and i installed a intake manifold and when i was messing around i found out there was an adjuster screw on the left side of the fuel rail underneath a cap. while i took off the cap a screw fell out and i found it and was wondering what this is for and what it adjusts ??? and should i tighten it all the way or not??

 

Thats the fuel pulsator.Did u mean u knocked the cap off and found an adjustment screw underneath the cap?Snap it back on and call it a day,as far as I know it requires no adjustment.

 

Ok I have a 97 integra gsr and i installed a new intake manfold and when i was messing around on the fuel rail and there is a little adjuster screw underneath this cap. What is it for? Thanks for ANY help.
