Description
Radium Engineering developed the 23in Fuel Pump Connector Harness for Walbro 255 around the needs of modified street and competition cars, where component compatibility and clean system layout matter as much as outright capacity.
Why This Upgrade Matters
Fuel-system electrical hardware has to carry pump current reliably in an environment exposed to heat, vibration and fuel vapor. Correctly sized wiring, sealed pass-throughs and secure terminals are as important to fuel delivery as the pump itself.
Product-Specific Details
Walbro fuel pumps are trusted by enthusiasts, tuners, and professional builders for their proven reliability, consistent fuel delivery, and performance under demanding conditions. Whether you're replacing a worn factory pump or upgrading to support additional horsepower, Walbro offers fuel pumps engineered to provide the flow your engine needs. Understanding Fuel Pump Flow (LPH) Fuel pump capacity is measured in liters per hour (LPH), which indicates how much fuel the pump can deliver. 190 LPH – Excellent for stock engines and lightly modified vehicles. Ideal for daily drivers and OE-style replacements. 255 LPH – A popular upgrade for naturally aspirated and mild forced-induction applications. Supports many street performance builds. 340–350 LPH – Designed for vehicles with larger injectors, increased boost, or ethanol-compatible fuel systems that require additional fuel volume. 450–525.
Fitment & Application
Application: Walbro 255
Fitment style: Application-Specific
Technical Notes
Pump wiring should be sized around real current draw and protected with appropriate relays and fusing. High-flow pumps can exceed the capacity of factory wiring, particularly when multiple pumps are operated simultaneously.

RAD17-0053
Enthusiast Notes
For a competition-oriented fuel system, clean wiring is reliability hardware. Use proper strain relief, circuit protection and grounding, and verify voltage at the pump under load.
Before Ordering
Confirm pump count, current draw, connector/terminal style and the vehicle' relay/fuse strategy before ordering.
