APPLICATIONS:
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 (). 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.
