F99 Fuel Pump Kit HP 1999-2000 RXP255
RFPK-001 - 1999-2002 LS1 Camaro / Firebird / Trans AM
FPA-001B Fuel Pump Assembly
* FOR USE IN 1999-2002 CARS WITH FACTORY ORIGINAL PLASTIC FUEL TANK AND PLASTIC FUEL MODULE ONLY!
FPWK-017W Fuel Pump Wiring Kit
The FPA-001B is recommended for factory HP upgrades to 600HP @ 58PSI using the factory lines and fuel pressure regulator. HP support may vary for N/A or F/I motors. Please factor in a 20-25% safety margin between what your motor needs and what your fuel system can supply. Our FPWK-017W wiring kit is highly recommended to maximize performance. Please contact your local Racetronix dealer to discuss your fuel requirements.
Why a universal pump can not be properly used in the 1999-2002 f-body:
The 1999 & up LS1 F-body cars have a pump that is inside a plastic fill-bucket. The fill-bucket is equipped with two inlets on the bottom. The equalization checkvalve is used to fill the bucket when the level of fuel in the tank is greater than in the bucket. The equalization checkvalve does not allow fuel to exit the bucket. The venturi system's inlet is a combination checkvalve and powered suction system. The factory pump supplies pressurized fuel via a small tube which feeds a calibrated jet inside the venturi system. This jet of fuel shoots across the base of the checkvalve inlet thereby creating a suction effect which draws more fuel from the bottom of the tank through the filter sock. This venturi system keeps the bucket full all the time even when the fuel tank is almost empty. A full bucket keeps the pump immersed in fuel regardless of the tank level so that when the tank is low on gas and you are doing some hard cornering or acceleration the pump does not run dry and start aerating (air bubbles) the fuel. This happens as the fuel sloshes from side to side in the tank leaving the center low on fuel. This can cause detonation and possible engine damage. The 99+ F-LS1 cars with plastic tanks have no baffling in them so the bucket is very important. The bucket also allows the car to operate with lower fuel levels in the tank due to its scavenging effect. The fill-bucket improves motor crank-to-run time as the priming time is reduced under most conditions. The return line feeds the pressure regulator on the fuel module which diverts fuel back into the bucket so that the unused fuel also helps keep it full at all times. Keeping the pump constantly immersed in gas within the bucket can extend the pump's life by not allowing it to be exposed to open air. Open air within the tank contains moisture and in time will cause the pump to rust / seize up especially if left to sit for long periods of time without the tank topped-up (i.e. winter storage).
What sets the Racetronix F99 pump assembly apart from others?
The Racetronix F99 pump assembly is equipped with an outlet which supplies the factory venturi system which is required to keep the factory system fully functional! All other pump solutions to date do not have this feature which requires a hole be punched in the bottom of the fill-bucket thereby dangerously disabling its functionality.
A factory-style fuel tube
is clamped to the pump's outlet for added reliability under high operating
pressures. When the fuel module is placed back in the tank it must compressed
causing the tube to bend sharply which can cause standard rubber hose to
kink and fail. The fuel tube is highly resistant to the additives in today's
pump gas which will attack and dry out even the best R9 and R10 rubber
fuel lines. This is why G.M. uses them as OE equipment.
The Racetronix in-tank pump
wiring harness eliminates the need for a wiring adapter or splicing which
can be unreliable and can cause performance loss. One end the Racetronix
in-tank harness has a Walbro connector that plugs directly into the pump
and the other end has a Delphi connector which plugs directly into the
sender. Teflon wire is used just like in the factory because
it is the most resistant to gasoline and its additives. We upgrade the
gauge of wire used from the factory to reduce voltage loss which maximizes
pump performance. All Racetronix harnesses are assembled using our computerized
crimp-quality monitoring system and then circuit checked for the utmost
in reliability. A truly plug & play wiring solution. Due to the age
of some F-LS1 cars much of the in-tank connectors are black / corroded.
The Racetronix harness replaces all these questionable components.
Racetronix Quality Pumps
The Racetronix FPA-001B pump assembly is based on Racetronix turbine pump technology which provides quiet reliable operation.
This kit has all the parts required to upgrade the factory wiring on GM factory vehicles equipped with the older-style 4-position 150-series fuel module connector to the new-style GT-series connector system. The older-style 150-series connectors are known to fail over time so GM/Delphi has switched all new-production modules to incorporate the GT-series connector system which has twice the current capacity. This fuel pump wiring kit is a must when upgrading to new high-performance pumps which draw 2-3 times more power than a factory pump.
This fuel pump wiring kit contains the following items:
Why use a Racetronix
Fuel Pump Upgrade 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 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 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 covered by our limited lifetime warranty.
