I got a vortech FMU of a mustang what do i hook the two fuel lines to? and I take it the vacum line goes to the intake.

 

The return line..

WHats the ratio on the mustang FMU? the f-body is 8:1

IIRC, a lot of the Mustang ones i've seen are 12:1. I don't know is this is universal

 

I can change the ratio no biggy, but which line goes where? The one line from the FMU goes into the bottom centre of the FMU and the other fuel line goes into the side of the FMU. Also does it matter what line goes to the fuel rail return and the return line coming from the gas tank? the FMU splices into the return line and blocks it when it sees boost increasing fuel pressure.

 

the fuel rail "return line" goes to the side fitting and the bottom fitting goes to the line that returns fuel to the tank. remember to use proper fittins to complete this install because FMU can raise the pressure to 80-100 psi and dangerous leak will occur. the FMU should have AN type fittings and buy two of these aeroquip items.

 

great thats exactly what i needed
