Which on is the main feed line and which is the return line? Is the main feed the line that goes right into the fuel rail as it comes in from the drivers side, or is it the line that connects with the hard line running accross the top of the fuel rail, and then goes into the FPR on the other side of the fuel rail? Pics with arrows would be greatly appreciated.

 

Didn't believe me? I know your just double checking...

The fuel line comes in on the right hand side of the fuel rail. On the left (when looking at the front of the car) the fuel pressure regulator is attached to the rail. After the FPR is the return line that is the hard gold colored line just above the fuel rail.

 

It's the one bolted to the fuel rail. The return isn't bolted, just hose clamped.

 

At this point I wasnt sure who to beleive, I asked four seperate evo owners, and it was 2 and 2 for each line. I downloaded the FSM and will sit there for three hours looking at it now.

 

the feed line is on the drivers side and the return is on the passenger side ( reason why the fuel reg. is on the passenger side) to pressureize the fuel system. So feed line is driver and return is passenger side

 

Thats where its tapped into. Thanks for your help, hopefully the 11 second evo club will let me in soon.
