[93BlkMustangGT]

I've just received a set of 42lb fuel injectors replacing the 30lb set that i have currently installed in my 93 GT. I will also remove the FMU, accordingly.


Question: with the FMU removed, what do i do with the 2 fuel hoses that are conneted to it?

you remove them and put the 2 ends of the fuel rail back together. dont forget to get a chip burned for the supercharger/injector combo

The return line was re-routed to the FMU. The vacuum line sensed the boost pressure and prevented the fuel being returned to the tank. That raised the fuel pressure in the fuel rail.

Usually you need to trace both the lines that were connected to the FMU back to where they intersect the factory lines. Using the proper tool disconnect those lines and reconnect the factory line to the fuel rail fitting.

thats what i said. remove the extra lines and at the ends of those lines will be a male and female fitting that will lock together.

You are correct. I just expanded your explanation a little further.
