Why a Racetronix Fuel Pump Upgrade Harness?

The Wiring Harness aka 'Hotwire harness'

No cutting, splicing, crimping or soldering. Retain factory configuration. Just plug it in and you are done!

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 ten-gauge stranded copper. This 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%. (Competitive harnesses typcally use wire which is one gauge thinner than ours). High-quality weatherproof fuse holders and relays are used for maximum reliability. The Racetronix harness has factory-type weatherproof connectors which plug directly into your fuel pump module/sender so no cutting or splicing is required.

UNIQUE FEATURES:

REDUNDANT GROUNDING SYSTEM: 
The Racetronix harness has a redundant ground upgrade as it is necessary to improve the pump's ground (-) supply as well. The Racetronix redundant ground upgrade clips onto the edge of the gas tank. Racetronix has integrated the harness ground into the main harness as a one piece assembly.  The ground clip helps improve the tank and pump ground. All grounds (including the factory) are routed back to a common piercing ring terminal which provides direct ground from the large tank strap bolt and body. This provides superior clamping force and grounding. The weatherproof relay shares this mounting location so that no mounting holes must be drilled. Silicon grease is provided to coat the grounding clip and ring terminal in order to prevent corrosion.

Harnesses made by other companies do not have this unique feature but rather they require you to drill / tap holes in your car to attach a seperate ground strap and mount your relay.To make matters worse they loop the factory ground in and out of the power feed connector to save the expense of running a dedicated wire. Running two wires into one seal does not allow it to seal properly so moisture could get in and corrode both the factory sender connector and upgrade harness.

The Racetronix harness is covered with Nylon loom (GM spec. GMP.PA6.003, -40ºF to 300ºF). Nylon loom is more flexible, slicker, shinier and has a higher temperature rating than the PE loom used by other vendors. Nylon loom provides superior protection and eases installation especially in colder climates.

POWER FEED: 
Our power feed comes off the back of the alternator where voltage is highest. It then runs through a weatherproof fuse holder which is mounted on the back of the alternator with a supplied stainless steel bolt. The TR has an unused hole in the back of the alternator which facilitates this fuse holder mounting quite nicely. This location keeps the fuse holder out of sight and the unfused wire down to a short 4 inches. Our competition's fuse holder must be remote-mounted requiring self tapping screws / holes. The unfused section of wire extends to the firewall.

Racetronix supplies a spare 20A fuse, 25 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.
