The \u003cstrong\u003eRadium Engineering DIY Fuel Pump Wiring Kit\u003c\/strong\u003e gives you everything to build a proper relay-switched power harness for one fuel pump, with a sealed relay and sealed in-line fuse holder that can live in weather-exposed areas. The aircraft-grade TXL wire shrugs off chemicals and heat, and the Raychem solder-based butt connectors make clean, reliable joints without a soldering iron.

The trigger side taps your existing fuel pump circuit with the included Posi-Tap, which matters for two reasons. First, the ECU's fuel pump output retains its priming behavior and its safety cutoff at 0 RPM. Second, on surge tank installs, tapping the primary pump relay wire makes all pumps run together, which protects against a pump running dry or an unattended fire hazard. Radium's diagrams assume a 12V trigger, and if your car switches ground instead, the relay coil simply wires with the opposite pole to 12V. Assembly requires wire cutters, a stripper, a crimp tool, a pick, and a heat gun for the solder sleeves. This is a build-it-yourself harness cut to your car's exact routing, so plan your relay location and wire runs before you start. The pump itself is not included.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Sealed relay\u003c\/li\u003e\n\u003cli\u003e1x Sealed in-line fuse holder with 20A fuse\u003c\/li\u003e\n\u003cli\u003eAircraft-grade TXL wire\u003c\/li\u003e\n\u003cli\u003eRaychem solder-based butt connectors\u003c\/li\u003e\n\u003cli\u003e1x Posi-Tap trigger wire connector\u003c\/li\u003e\n\u003cli\u003eRing terminals (battery and pump connections, including Bosch 044 style)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal: powers one 12V electric fuel pump per kit\u003c\/li\u003e\n\u003cli\u003eFuel surge tank pumps, in-tank pump upgrades, and external pumps such as the Bosch 044\u003c\/li\u003e\n\u003cli\u003eMulti-pump systems: purchase one kit per pump\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672688230467,"sku":"17-0031","price":75.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-17-0031-11951038562374_3ac7bafd-e2b3-4054-a25d-790bdcef4e65.jpg?v=1786717047","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-diy-fuel-pump-wiring-kit-17-0031","provider":"Tuned by Shawn","version":"1.0","type":"link"}
