Hey guys
I just got my spool stage 1 kit and I'm ready to install it but I have a problem trying to understand how to install the FMU the installation guide doesn't really guide you that good .

HELP PLEASE THANKS
 
The very top is where you should have a vacuum source going to the FMU... then you have two fittings on the bottom. The one that is all the way on the bottom is the OUT... the other is IN. The IN should be a line coming after your OEM FPR, and the OUT is returning fuel back to the tank. So just picture your fuel line after your OEM FPR... the FMU should be inline with it.
 
Hey Rob I'm still a little confuse on the fuse line that goes to the FPR is removed what do you do with that line dosen't it go to the bottom of the FMU .
I think my install guide must be missing the page were it say THE NEXT PICTURE ILLUSTRATES THE FACTORY FUEL LINE THAT WILL NEED TO BE REMOVED. and the next page isFMU mounting location. and doesn't say what line to remove.
 
Take the fuel line that is coming out of your FPR.. which should be your return line.. cut that and put the end that is attached to the FPR to the middle fitting on the FMU... then the other side of the hose (that runs back to the tank) is attached to the bottom of the FMU.
 
Now I got it I always thought it was the suppy line I didn't know that it was the return line . All I need now is the 90 deg. elbow that goes to the throtlle body its back order.

Rob thanks for the help I really appreciate it.
