Vortech Maxflow Fuel System - Manual

Maxflow fuel system installation instructions
1986-1993 Ford 5.0 Mustang
WARNING: Keep a fire extinguisher handy and use extreme
caution when dealing with fuel and fuel system components.
Make sure that all work outlined below is performed in a well
ventilated work area, away from any possible flame or spark.
Vortech Engineering, Inc. is not responsible for engine or ve-
hicle damage due to fuel leakage, fire or pump failures.
A. Component removal/Preparation
1. Disconnect the negative cable from the battery. Secure cable so that it
will not accidentally fall back onto the battery terminal.
2. Disconnect the factory fuel feed and return lines from the fuel rail using
a springlock disconnect tool. Remove the fuel rail extension tubes that
connect the rail (feed and return) to the body mounted fuel lines.
3. Remove the upper intake manifold.
4. Raise the rear of the vehicle and secure with two 2-ton jackstands. Drop
down the fuel tank by loosening the filler neck and removing the two tank
support straps. Unplug the wiring harness attached to the body.
Temporarily remove the tank vent hose.
5. Disconnect and remove the original flexible feed and return lines running
to the tank. Separate both lines from the vehicle.
6. Unplug the factory harness that connects to the in-tank fuel pump (NOT
the fuel level sending unit harness). Using electrical tape, wrap the
exposed end of the harness to protect the contacts from grounding out
on the body or fuel tank. Use tie-wraps to secure the now unused fuel
pump harness to the fuel level sending unit harness.
7. Spray the top of the fuel pump (not yet removed from the tank) with
aerosol brake cleaner so that no dirt or debris will fall into the tank when
the pump is removed. Remove the factory intank fuel pump assembly
and set aside.
8. Locate the four supplied aluminum Y-block adapters in the Maxflow fuel
system kit. Using pipe thread sealant, install one each of the supplied
1/8” NPT pipe plugs into the 1/8” NPT port on the top of each of the Y-
blocks. Set aside the prepared Y-blocks for future use.
NOTE: Make sure that the fuel level is below 1/4 tank for easier
installation
