{"product_id":"fuel-pump-wiring-harness-upgrade-kit","title":"Fuel Pump Wiring Harness Upgrade Kit","description":"The Racetronix FPWH-052 is a comprehensive electrical upgrade system engineered specifically for the 1997-2003 C5 Corvette, designed to ensure optimal performance and longevity for high-output fuel pumps.\n\nFactory fuel pump wiring is often inadequate for modern performance pumps, which can demand significantly more current than original equipment. This can result in voltage drop, overheating of connectors, and ultimately, fuel pump failure. The FPWH-052 kit fundamentally re-engineers how power and ground are delivered to the pump. By converting factory ground circuits into a dual-positive feed, it effectively doubles the current capacity through the bulkhead connector.\n\nThis kit provides a robust solution that allows your fuel pump to operate at its rated capacity without taxing the vehicle's existing electrical infrastructure. It features a high-output wiring harness (FPWH-052HD), a Delphi 4-way Metri-Pack bulkhead connector assembly (BCA-4W), an in-tank harness (ITWH-055) for Sumitomo\/Tyco connectors, and a booster interface connector (PBIC-001) for voltage booster integration. The system includes spare fuses, cable ties, and silicone grease.\n\nKey engineering advantages include a doubled current capacity (upwards of 28 amps), precision ultrasonic termination for the main 10AWG power feed, and readiness for pump voltage boosters. The in-tank harness ensures redundant negative grounds for reliable operation. The dual-positive bulkhead design bypasses the Metri-Pack 150 terminal bottleneck, and perimeter grounding utilizes the module's mass as a high-current bus. It's important to note that this harness is exclusively for a single fuel pump and cannot be used for dual-pump setups. Furthermore, it relies on the factory fuel pump circuit for relay triggering, so existing issues like melted relay terminals in the under-hood electrical center must be addressed separately, though a bypass procedure from the PCM is available. Professional installation is recommended.","brand":"Racetronix","offers":[{"title":"Default Title","offer_id":52663409213752,"sku":"FPWH-052","price":150.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687134688.jpg?v=1784326674","url":"https:\/\/store.motormia.co\/products\/fuel-pump-wiring-harness-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
