The only reason i ask is because i'm running an MSD inline fuel pump on my turbo setup and wanted to change my fuel lines to stainless steel so i was checking out the Russell Performance sites and i think i have to just buy the banjo fittings and custom the lines. Heres the site and i'm thinking i have to either buy part number 640910 or 640920 but i dont know if my 1994 Civic DX (d15b7) has a fuel pressure damper or not. I dont even know what a fuel pressure damper is. Please help! thanks

 

a fuel pressure dampener eliminates the fluctuation of fuel pressures when the injectors are opening and closing, without one the injectors won't spray the correct amount of fuel perfectly. A fuel pressure regulator controls fuel pressure depending upon the engine load (through manifold vaccuum). I suggest getting one with a fuel pressure damper since you're modifying your fuel system which is a mpfi (multiport fuel injection) type system.
