help with fuel rail object...

[aznsiko]

can somebody tell what is the device or object that is located on the far left on the fuel rail on a B18A1? it looks like a regulator of somesort.. there is a cap and once the cap is removed then underneath is a screw.. does anybody know what the effect of loosening or tightening the screw will do??

sorry i have no pics.. but would make it a lot easier if i did...

well yeah please identify it for me guys..

Acura is calling it a “Pressure Diaphragm”. “It’s to help the fuel pressure regulator with maintaining proper pressure and also lets air out of the system.” that’s what the tech said. I took mine off when I boosted it and ran an aftermarket FPR and fuel setup.

i heard of it referred to as a "suppressor" previously...

i found my screw had fully fallen out once azinsicko - so i screwed it back in...

i doubt it affects performance in any way...

Nope, mine broke in the little hole, fell out been swapped now its gone! I found it did nothing for me.
