Anyway, does anyone know if series 5(89-91) primary fuel rail is compatible with GSL-SE(84-85) fuel rail? I heard that the later fuel rail have better designed fuel pressure pulsation damper and don't fail as often. But want to be sure I should get it before I go buy it.



Mine is faulty and the screw has fell out on the damper, however its not leaking......YET.

 

if all else fails try this should add a little spice to your life
