Show original supplier description
The Racetronix C43 Fuel Pump Assembly is a high-performance upgrade for the 1984-1985 C4 Corvette, built around the RXP255 255LPH turbine fuel pump. This pump is engineered for reduced noise and increased reliability, even with ethanol-enhanced fuels, and is capable of supporting up to 550 rear-wheel horsepower at 13.5V and 43.5 PSI when used with compatible wiring. This comprehensive kit includes a 30-micron filter sock for superior filtration compared to the factory 70-micron sock. It also features a direct-hookup, heavy-duty Teflon harness that is E85 compatible and eliminates the need for adapters. The assembly comes with high-pressure fuel line, stainless steel FI gear clamps, a pump mount grommet, and a pump sound insulation sleeve to minimize noise. Additionally, it includes a C4 fuel tank gasket and a full set of nine stainless steel hex-head tank bolts, washers, and o-ring seals, providing a complete solution for replacing aged or corroded components. Installation may require attention to the vehicle's bulkhead connector. Racetronix strongly recommends replacing C4 Corvette bulkhead connectors, which are often in poor condition, with their BCWA-C43 wiring assembly to prevent wiring failure and potential motor damage. Furthermore, customers have reported that some C4 hanger wiring is incompatible with standard in-tank harnesses due to GM using random leftover inventory. It is crucial to confirm compatibility with the C43-type in-tank harness before installation, and purchasing the BCWA-C43 is advised if uncertainty exists or the existing harness is in poor condition.
