Hi guys, I have what i think (IIRC) is a SX adjustable fuel pressure regulator but not sure if it matters which way round its fitted. Got it second hand and it has a take off on the bottom and one on the side so which was does the fuel flow through or does it not matter? There is no markings to say flow direction.

Cheers for any Info!

Bottom is return, one on side is the incoming from the fuel rail.
Some pics of a 3 port one used in a parallel setup here.

 

Thank you!
