The Racetronix LS1 fuel pump module is a direct drop-in replacement
for the factory GM plastic pump assembly. No modification is required to
the factory sending unit. Simply remove the old plastic pump assembly and
put in the new one. Installation of the Racetronix LS1 fuel pump module
can be easily done in under 5 minutes with basic hand tools. The Racetronix
fuel pump module is designed to position the pump in the factory location
for optimal performance. Should the pump ever require service, it can be
removed from the module using the supplied hex key by removing two of the
mounting dowels. The Racetronix pickup adapter allows the factory filter
sock used on the Walbro pump which has a much greater surface area than
the after market types thereby providing longer filter service life. Retaining
the factory filter sock also allows the GM return system be kept intact
thereby reducing contamination and foaming. The Racetronix LS1 fuel module
is made from T6 high-grade aluminum which is bright dip anodized and sealed
for long life. A factory style Delphi fuel feed line is double-clamped
to the pump's outlet for added reliability under high operating pressures.
This Delphi feed line is more flexible than a rubber line making for easier
installation. The Delphi feed line is highly resistant to the harsh chemicals
in today's gasoline which tend to attack and dry out rubber fuel lines.
The Racetronix in-tank pump wiring eliminates the need for an in-tank wiring
adapter or butt connectors which can be unreliable and can cause voltage
drop. The Racetronix in-tank pump wiring has a Walbro connector that plugs
directly into the pump. The other end has Delphi terminals which are easily
inserted directly into the factory bulkhead connector. Teflon
wire is used throughout as is done from the factory. Teflon
wire is the most resistant to gasoline and provides maximum voltage to
the pump. All connections are crimped and soldered. This approach improves
the overall reliability of the connections and guarantees maximum performance.

RACETRONIX WIRING HARNESS
High performance fuel pumps
need a good power source in order to perform to their full potential. On
average a Walbro high-performance fuel pump requires twice as much power
as a factory fuel pump. Factory wiring is just enough for a factory pumps
power requirements because manufacturers need to save cost and weight.
Racetronix field tests have shown that running a high-performance fuel
pump off of the factory wiring can cut pump performance by 30% or more.
Problems with failing factory relays, connectors/terminals and fuse contacts
are also common when excessive load is placed on them.
The Racetronix plug and play
harness is designed to remove all fuel pump load from the factory pump
circuits while providing the pump with a new heavy-duty power source. The
Racetronix harness gets its power directly from the alternator's battery
terminal. The voltage at the alternators output is typically 1-2 volts
higher than at the battery when the motor is running (high charge/load
conditions and WOT). This means that your Walbro high-performance pump
can provide as much as 20% more fuel in some cases. The Racetronix harness
uses high-quality automotive-grade wire which is resistant to oil, gas,
heat and rot. The main length of wire in the Racetronix harness is three to four gauges thicker than factory wire
which helps reduce resistive power loss to almost non-existent levels.
This helps improve pump performance by as much as another 10-20%. High-quality
weatherproof fuse holders and relays are used for
maximum reliability. The Racetronix harness has factory-type connectors
which plug directly into your fuel pump module/sender so no cutting or
splicing is required. The Racetronix harness has a redundant ground upgrade
as it is necessary to improve the harness on the negative side of the pump's
supply as well.
There is nothing worse than
being in the middle of an installation only to find that the manufacturer
has skimped on installation hardware. This is why Racetronix supplies a
spare ATM fuse, 25 black nylon wire ties, silicon grease and stainless
mounting hardware with each kit.
Racetronix harnesses are
considered the best by which all others are judged. Attention to detail
in every Racetronix harness is evident at first glance. Racetronix spares
no expense to ensure reliability, ease of installation and performance.
All Racetronix harnesses
are assembled using our computerized crimp-quality monitoring system and
then circuit checked for the utmost in reliability. This harness is backed by our limited lifetime warranty.
An optional battery to body
ground upgrade kit is available. This kit upgrades the under-rated
factory ground wire running from the battery to chassis. It includes a flexible 8 gauge copper wire and battery
nuts with accessory taps. We highly recommend this inexpensive option because
this is a weak point in these cars.
The Racetronix harness comes
equipped with an interface connector just after the relay (see
product picture above). This connector in combination with an optionally
supplied connector set allows for easy plug and play addition
of a pump booster / voltage amplifier such as the MSD or KB units. These voltage amplifiers / boosters will allow the Racetronix single in-tank pump system to support an additional 100-200 flywheel HP (B.S.F.C. dependant) when run at 16-17 volts. This configuration
offloads the excessive current draw placed on the factory wiring onto the
heavy gauge Racetronix harness system. System diagnosis becomes easier
by simply being able to unplug, isolate and bypass sections of the wiring
