Default 1998 GT & 2003 Cobra Evap schematics

Hey all. Did the 2003 Eaton swap in my 1998 GT and had to upgrade to the 2003 tank. The evap system piping is different and I was hoping to get the schematics to rig it up somehow. Also, I did the EGR delete and had the EGR system shut down in the tune. Does it even matter if I get the piping correct? Should I just cap them off? Thanks for your thoughts.

Using google to find each years evap pdf schematics would be easier and simpler than us trying to explain. But I would suggest keeping your evap on your 98 since you are using a returnless factory fuel system.

I found this a while back while I was tossing the idea of using a 03/04 baffled tank

Very helpful, thanks. I'll use the pics to see if the 98 is the same as the 99.

Believe it or not I have a 1998 GT and it has a return style fuel system, even the haynes manual says 98's are returnless and everything on the "interweb" says the same thing but i got one.
