i have a JDM S4 TII motor in my 86 base model.
my question is what is the order for the JDM fuel lines.
Here is a picture of how they are hooked up


blue is coming from the filter
red is the return line
green was cut off by the engine supplier and I would like to know where it goes

thanks

the green on goes to evap.

to do this properly you should remove the upper intake and inspect things, like vacuum lines, grommets etc.

anyway, try to trace the fuel lines. the one that goes to pulsation dampner (JDM secondary rail) is supply. the one that goes to press reg (on JDM is on primary rail) is return. use flash light, or you can tepmorary remove fuel line at the secondary fuel rail at firewall and blow thru, to verify the hardline order.
