Vortech Superchargers Maxflow Fuel Pressure Optimizer Installation guide

  • Hello, I'm your chat assistant. I have reviewed the installation instructions for the Vortech Fuel Pressure Optimizer for 86-95 Mustangs. This document provides a step-by-step guide to install the optimizer, including preparation, component removal, and fuel pressure adjustment. I'm ready to answer any questions you have about the installation process or the device itself.
  • What should I do before starting the installation?
    What size hex key is needed for the optimizer screws?
    What size hex key is needed for fuel pressure adjustments?
    What is recommended to use on screws?

A. Component Removal/Preparation
1. Disconnect the negative cable from the battery
negative terminal.
2. Disconnect the vacuum line from the regulator.
Remove the screws securing the fuel regulator to
the fuel rail.
3. Referring to the graphic assembly diagram, mea-
sure down 1/4" from the top of the fuel regulator
and mark the location. Cut the upper portion of
the fuel regulator top off and discard.
4. Install the O-ring onto the factory fuel regulator
and seat onto the lip. Install the Vortech® fuel
optimizer as shown in
Fig. 1
. The adjustment
screw should be unscrewed as far as possible to
ease installation. Using a 7/64" hex key, tighten
the four supplied 6-32 x 1/2" stainless steel
screws evenly, using a criss-cross pattern.
There
is no need to tighten screws excessively
. A small
amount of blue loctite 247 is recommended on
each of the four previously mentioned screws.
5. Reinstall the fuel regulator using the previously
removed hardware and tighten to the vehicle
manufacturers torque specifications.
6. Reconnect the vacuum line to the regulator. Re-
connect the negative battery cable to the battery
terminal.
7. Turn the ignition switch on, but do not operate the
starter. After the fuel pump has run for approxi-
mately two seconds, the fuel pressure in the fuel
line will rise. Repeat this two or three times, then
check for any possible fuel leaks.
8. Adjust the fuel pressure to the desired setting
(turn clockwise to raise fuel pressure) using a
5/32" hex key and secure this setting, tightening
the jam nut against the regulator cover.

NOTE: Inspect the fuel regulator O-ring for
cracks and tears. Replace if necessary.
