It may not have one. Many cars now have the fuel pressure regular in the tank and only one line to fuel rail


This is a spot that still had lines has 5 lines 2 are break lines other 3 i assume are fuel one for feed how many lines run up for emissions ?

Ok well you should then have one that is for purge and one for supply. Two for brakes. It does have 5 lines ? If it does the you do have a return line. Are you trying find where it goes on tank or where it goes in the engine area ?

I just looked up your fuel system. It only shows one fuel line with the regular in tank. It also show a vacuum line to EVAP canster. So I do not think you have a fuel return line. I wish I could post a picture of the fuel and vacuum line diagram. I hope this helps


Thank you i am jus trying to get it up and goin the evap system is gone previous owner removed it i guess and i know ur not supposed to run with out it but what can u do in a pinch there no emissions were i live i got new tank and am just gonna worry bout fuel lines and vent it to atmosphere like olden days so ur best guess is saying that there is no return line i did look at fuel rail only one line on it so i can jus run new line to fuel pump and one to vent it and all should be good ?


So i see 2 are brake lines one is supply line one runs to air filter box and one runs to module then to intake can i jus run supply line and cap the other two lines guessn they are both emission related
