does anyone know if the fuel system in an 03 lancer oz is a return system and not returnless? trying to convert my 04 RA's returnless fuel system into a return system and i know the 02-03 es lancer's fuel pump is setup for a return system but im not 100% sure about the oz...im sure its the same i just need confirmation

 

02-03 are returned... 04-06 are returnless... There is no difference under the hood for 02-03 es, ls, and oz...

 

K..thanks thunder
