Why use a Racetronix Fuel Pump Upgrade Harness?
The Wiring Harness
All fuel pumps are voltage sensitive, the
lower the voltage the lower the fuel volume. Gerotor pumps exhibit a significant
increase in fuel volume with increased supply voltage. A Walbro pump's
average fuel volume increases over 18% by increasing the supply voltage
from 12 to 13.5 volts. The factory harness is marginal at best for supplying
a factory pump with enough voltage to perform well. This is why the 'hot
wire' modification is so popular. Replacing the factory pump with a high-performance
pump can easily double the current demand under W.O.T. pressures.
The voltage drop in the factory harness increases proportionally to the
current demands of the pump. Racetronix has documented tests where the
voltage drop in a factory harness has caused over a 25% drop in fuel pump
volume. The Racetronix harness uses heavy 10 gauge copper wire to reduce
voltage-drop to very low levels. The factory gauge of wire used is three gauges thinner. Our power feed comes off the back of the alternator where
voltage is highest. It then runs through a Delphi weatherproof fuse holder
and then to the back of the car. The Racetronix harness uses three-position
male and female weatherpack connectors which plug in-line with the
factory harness at the back of the tank. No cutting or splicing is required. High-quality
weatherproof fuse holders and relays are used for
maximum reliability. 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. Racetronix supplies a spare ATM fuse, black vinyl
wire ties, silicon grease and 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 Racetronix harness is backed by our limited lifetime warranty.
UPGRADE
OPTIONS
BGK
An optional battery to body
ground upgrade kit is available (P/N BGK8). This kit upgrades the under-rated
factory ground wire running from the battery to the chassis. It includes
an 8 gauge copper wire fitted with terminals and battery nuts with accessory
taps. We highly recommend this inexpensive option because this is a weak
point in these cars.
PBIC
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 (P/N PBIC) 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
system.
The 3-position tank-end harness connectors and harness lengths are compatible with the cars listed below.
V6 cars or V8 cars without a serpentine belt system may require that the harness fuse holder be mounted in a different fashion or location.
This harness is not compatible with 1982-1984 f-body cars.
Customers with 1982-1984 f-body cars must contact our sales department to special order a harness which is compatible with their chassis and fuel sender.
