1998-2002 LS1 F-Body Fuel Pumps & Controllers

The Pumps

The Racetronix F-LS1 pump assembly is based on Walbro gerotor pump technology utilizing the most powerful armature and gear set currently available. Walbro has set the industry standard in high-performance in-tank pumps. Walbro pumps are QS9000 certified and are used as OE equipment in many production performance vehicles such as the C5 Corvette. Walbro's gerotor design is able to maintain high pressures while providing high volumes as well. This is done by squeezing the fuel out between two gears instead of pushing it like most factory vane pumps do. (i.e. factory F-LS1 pump). This positive displacement design makes high-performance Walbro pumps small, light weight, quiet, efficient and reliable. Tests in the field have proven the Racetronix F99+ system will support upwards of 600RWHP and 700RWTQ in some applications.

The 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 pump’s 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 alternator’s 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%. High-quality weatherproof fuse holders and 40 amp silver-contact 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.

UPGRADE OPTIONS

135-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.

135-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 up to 700RWHP 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.

Adding a turbo or supercharger to your engine is a great way to improve the power of your car. But you have to remember that when more air is being pushed into the engine, the need for additional fuel raises proportionally. Meeting these new fuel demands could mean larger injectors or ECU programming, both which can be pricey. This new Fuel Pump Booster is the economical (and easy) answer for your engine’s new fuel demands.

The Booster will supply the electric fuel pump with increased voltage in relation to the manifold boost pressure. As boost pressure increases in the manifold, the MSD Booster will increase the voltage to the electric fuel pump. The amount of voltage is adjustable with a potentiometer from a range of an additional 1.5 volts to a maximum output of 22 volts over a range of 5 – 30 psi.

With their unique combination of ultra-high performance, durability, and reliability, Aeromotive's in-line pumps leave the competition behind.  All Aeromotive fuel pumps are designed to meet the high-performance demands of your application with durability and reliability. Whether you're running 2000 HP or 200 HP, carbureted or fuel injected, our pumps optimize flow and line pressure.
