Why a Racetronix Fuel Assembly?
Racetronix direct-fit HP Turbine Jet Pump:
The RXP255J turbine pump is a direct-fit replacement for the factory Walbro jet-pump. Direct-fit means no modification to the fuel module is required therefore the full functionality of the fill bucket is maintained. The fill-bucket allows the fuel pump to use its jet + venturi function to keep the pump immersed in fuel at all times regardless of the tank fuel level. This aids in preventing fuel starvation under hard cornering and acceleration. Keeping the pump immersed in fuel also helps prevent moisture damage which can shorten the pump’s life. The RXP255J pump has the same flow as other Walbro 255LPH pumps but since this pump is run at a base pressure of 58PSI (vs. 43.5PSI) its flow rating drops to a nominal 225LPH @ 13.5V. There are no Walbro pumps which are spec’d at 255LPH @ 58PSI @ 13.5V. This has been a constant source of confusion on car forums due to misinformation being posted. This pump assembly in combination with our upgrade harness FPWH-007 will support APPROX. 550-600RWHP using the factory regulator and fuel lines.
* Our FPWH-007 is required for a HP pump to meet stated performance specifications because the factory wiring was not designed to handle high-performance pumps which draw more than twice the power of a factory pump. A performance reduction of 15-25% in pump performance can be expected along with reduced reliability when a HP pump is run off the factory harness.
GM type no-kink solvent resistant fuel tube:
This fuel tube is the same type used by GM from the factory. The fuel tube is kink-resistant thanks to its ribbed design. Its special composition makes it more resistant to the solvents in today’s pump gas (i.e. toluene, Xylene, MTBE, Ethanol) as compared to rubber / neoprene which dries out, swells and cracks.
Upgraded 14 gauge Teflon in-tank harness (C5-ITWH):
Racetronix has upgraded the factory Teflon wiring from 16 gauge to 14 gauge multi-strand copper wire. This helps reduce voltage drop and at the same time maintains the same level of resistance to fuel solvents as the factory wiring. Generic Walbro kits do not use Teflon wire but rather a much less expensive plastic type.
Direct-power pump wiring (no adapters / splices):
The Racetronix in-tank wiring harness is a one-piece assembly. One end has the Walbro connector and the other is fitted with GM type terminals which are installed directly into the factory connector making it true plug & play. Generic wiring harnesses require cutting and splicing of the factory wiring.
Redundant in-tank ground loop (solves factory problem):
The factory in-tank wiring has the ground from the pump and ground from the power connector split into two circuits which relies on push-lock terminals and the module’s body as a ground junction source. We have seen these connectors lose and in some cases corroded. If one were to fail the pump would lose power. Racetronix has redesigned the grounding system with a daisy-chain / loop through circuit. This way there are three grounds all tied together thereby making circuit failure almost next to impossible. An extra ground is also provided via the external upgrade harness via a ground lug. This further enhances the fuel module’s grounding system and eliminates the chance of a floating ground condition. A floating ground condition will cause a static buildup and potential fuel ignition. All harnesses are assembled using our computerized crimp-quality monitoring system and then circuit checked for the utmost in reliability.
Fuel Screen / Silicon gasket seal:
A new replacement filter screen and silicon pump seal are provided.
