                                     SUMMARY




          %—TEK Industries of P.O. Box 381, Devault,    Pennsylvania 19432,   has

applied for exemption from the prohibitions in Section 27156 of the California

Vehicle Code for the Fuel Tweak device.        The device is designed for

installation on 1992 and older model—year light—duty vehicles with multi—point

fuel injection and carburetion as listed in Appendix A.

          Previously the Air Resources Board (ARB) exempted three similar devices;

"Fuel Charger" by J. A. Lance Company, Inc.,       "Fuel—Energizer" by the Magnetizer

Group, Inc. and "Magna Charger" by B & D Research and Development.          Based on

the engineering evaluation of the Fuel Tweak device and exemptions issued for

the devices that operate in a manner similar to the Fuel Tweak, the staff

believes that the Fuel Tweak will not have any adverse effects on the exhaust

emissions from light—duty vehicles with multi—point fuel injection and

carburetion as listed in Appendix A.

          The staff recommends that the Fuel Tweak device be exempted from the

prohibitions in Vehicle Code Section 27156 and that Executive Order D—257 be

issued.

          FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION
            27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE
                       CALIFORNIA CODE OF REGULATIONS



I.     INTRODUCTION

       Z—TEK Industries of P.O. Box 381,   Devault,   Pennsylvania 19432, has

applied for an exemption from the prohibitions of Vehicle Code Section ({VC)

27156 for the Fuel Tweak device.    The device is designed for installation on

1992 and older model—year light—duty vehicles with multi—point fuel injection

and carburetion as listed in Appendix A.    The applicant submitted installation

instructions and specifications of the device for our evaluation.




II.    CONCLUSION

       Previously, the Air Resources Board (ARB) exempted three similar

devices; "Fuel Charger" by J. A. Lance Company, Inc.,     "Fuel—Energizer" by the

Magnetizer Group,   Inc. and "Magna Charger" by B & D Research and Development".

Based on the engineering evaluation of the device and the exemptions issued to

other devices that operate in a manner similar to the Fuel Tweak, the staff has

determined the Fuel Tweak will not have any adverse effects on the exhaust

emissions from light—duty vehicles with multi—point fuel injection and

carburetion as listed in Appendix A.




III. RECOMMENDATION

       The staff recommends that Z—TEK Industries be granted an exemption from

the prohibitions in California Vehicle Code Section 27156 for the Fuel Tweak

device and that Executive Order D—257 be issued.


IV.     DEVICE DESCRIPTION

        The Fuel Tweak consists of two magnets secured on opposite sides

of the vehicle‘s fuel line.    Each Fuel Tweak magnet is a three, four or high—

powered two inch long, depending upon the model, with a 1/2 inch square cross—

section enclosed in an aluminum bracket.     The assemblies are covered with vinyl

protective coating.     The brackets are designed to attach to the fuel line with

‘nylon ties.   The device‘s installation instructions and a drawing are shown in

Appendices B and C respectively.




v.      DISCUSSITON

        Z—TEK Industries claims that the Fuel Tweak, when installed on a

vehicle‘s fuel line, magnetically treats fluid hydrocarbon fuels.       The

manufacturer stated the device is configured so two different magnetic fields

act upon the incoming fuel charge.    The manufacturer also claims this device

increases horsepower.     The ARB did not perform any testing on the device to

substantiate the claims made by the manufacturer.     However,   it is the staff‘s

opinion that the technical principles underlying the stated function of the

device are not capable of producing any effects on emissions or engine

horsepower.

       The ARB previously exempted three similar devices;    "Fuel Charger" by J.

A. Lance Company, Inc.,    "Fuel—Enérgizer" by the Magnetizer Group, Inc. and

"Magna Charger" by B & D Research and Development",    Because of previous

exemptions issued to similar devices with the same operating principle as the

Fuel Tweak and the fact that qualifying for an exemption is based on not

adversely affecting exhaust emissions, the staff recommends that Z—TEK

Industries be granted an exemption as requested.

                                                                    VW JETTA, GOLF, BV GTI
                                                                    with Digifant® fuel injection.



                     ON THE INCOMING FUEL LINE,

  Diagram one shows the measurement points on the incoming fuel line where the protective
  tape is to be applied. Use a tape measure to determine the exact locations.

  This tape protects the fuel line from possible wear from the plastic cable ties used to hold the
  FUEL TWEAK"* in place.

                                                 TM



  Using the four shorter plastic cable ties as shown in diagramtwo, install the unit Iposely
  around the incoming fuel line. For now, leave plenty of slack in the cable ties to allow for unit
  positioning.

 it is best to position the locking tabs at the corners of the unit, not halfway up the sides. This
 will minimize any slack once the cable ties are tightened in STEP SIX.


&P EIVE : ALIGNMENT OF THE FUEL TWEAK® ON THE FUEL LINE. THIS is VERY
           MPORTANT.
 Section A : Position the FUEL TWEAK""* unit so that the outer two cable ties go around the
 two protective tape strips that you just installed. diagram

 Section B: The FUEL TWEAK""* is designed so that the two oppossing halves of the unit are
 offset lengthwise by about 1/2 inch. This overhang must be adjusted to exactly 1/2 inch if
 measured from the ends of the FUEL TWEAK®*". diagram This adjustment is done
 by sliding the units slightly together or apart lengthwise along the fuel line. This overhang of
 exactly 1/2 inch optimizes the unit‘s effectiveness and provides maximum power output from
 the treated fuel.

 Section C : Twist the unit on the fuel line so that it is in a horizontal position and will lie flat
 against the bottom of the air duct when it is replaced.


  TEP    SIX :   TIGHTENING   THE    CABLE TIES.

 Keeping the above mentioned sections from STEP FIVE in mind, carefully tighten the cable
 ties to remove cable tie stack from around the unit. Now the unit should not be able to slide
 along the fuel line. DO NOT OVER—TIGHTEN — this could pinch or squeeze the fuel line. The
!“)er fuel line should maintain a shape under the cable tie tension.

  TEP    SEVEN :     CUT   QOFF   EXCE   ABLE TIE TAB LEN         :

 Use wire cutters to trim cable tie ends. You may want to leave 1/2 inch tabs. This will be
 helpful if further tightening is required in the future. Periodically check the cable ties for
 excessive looseness. Make sure that no sharp edges from the cable ties will rub against
 other rubber lines or wires.

 * Check the unit once more to be sure that the overhang is exactly 1/2 inch.
 The FUEL TWEAK** unit should be installed in such a way that it does not magnetically stick
 to any steel brackets or engine parts. This would detract from the unit‘s effectiveness. Again,
 keep the unit at least six inches away from the engine‘s computer brain at all times.


  TEP EIGHT :      SECURE THE FUEL TWEAK FROM ANY MOVEMENT. RE—INSTALL AIR
                DUCT.
  he weight of the FUEL TWEAK"* unit must be suspended to keep it and the fuel line from
   gging or swaying during spirited driving.

Section A : Thread the fifth and longest cable tie through the two central cable ties on the
bottom of the unit that have just been tightened. This cable tie will loop up and around the air
duct after it has been replaced.

Section B : Remove the two rags covering the openings of the intake manifold and air filter
housing. Re—install the air duct and properly tighten the hose clamps.

Section C : Loop the cable tie up and around the air duct. Tighten it securely to eliminate any
movement of the unit or the fuel line during driving. Cut off excess cable tie tab length.

Double check the work you‘ve done. Re—inspect your installation after a week‘s worth of
driving has passed. Check to see that the unit is secure and is not slipping along the fuel
line. Tighten the cable ties more if necessary but make sure that the fuel line maintains its
