Walbro Universal 190 LPH External Inline Fuel Pump Kit
Engineered by an industry leader in high-performance fuel delivery, this genuine Walbro 190 LPH High-Pressure External Fuel Pump delivers the rock-solid reliability and superior hot-fuel handling required by demanding race and production vehicles worldwide. This external inline pump is an excellent choice for custom EFI conversions, secondary booster setups, or performance upgrades where an in-tank installation is impractical.
Flowing a consistent 190 liters per hour (LPH), this high-pressure unit safely supports up to 350 HP (at the crank) when supplied with standard alternator operating voltage (13.5V to 14.2V). Designed to operate across a broad 0 TO 50 PSI range, fuel delivery is dictated by your fuel pressure regulator-making it a perfect high-volume companion for stock Toyota EFI configurations (which feature a baseline pressure of 42 PSI) as well as adjustable aftermarket setups.
Key Features & Benefits
- 350 HP Power Capability: Delivers a high-pressure, 190 LPH flow rate optimized for naturally aspirated and mild forced-induction builds.
- Chassis-Mount Convenience: Mounts inline externally along the vehicle frame rail, simplifying plumbing adjustments and eliminating the need to drop the fuel tank.
- Superior Hot-Fuel Handling: Advanced internal rotor architecture resists vapor lock and maintains stable fuel line pressures under extreme engine bay temperatures.

Critical Installation & Warranty Guidelines
Mandatory Pre-Filter Requirement: The leading causes of premature inline fuel pump failure are debris ingestion and overheating-neither of which are covered under the manufacturer's warranty.
- You must install a 20- to 40- micron pre-filter inline between the fuel tank and the pump inlet to protect the internal precision gears.
- Thoroughly flush and clean your fuel tank prior to installation to remove old sediment, rust, or debris. Never run this pump dry.
System Notes & Tech Support
- Regulator Upgrade Recommendation: Because fuel pumps rely on the regulator to dictate system pressure, we highly recommend inspecting, servicing, or upgrading your stock fuel pressure regulator if it has been in service for an extended period.
- Fitment Modification: This is an aftermarket performance upgrade; minor fabrication, bracket adjustment, or custom line plumbing may be required depending on your specific chassis layout.
- Tech Line Available: If you have thoroughly reviewed the included instructions and require technical or plumbing assistance, please contact our internal technical support line for expert guidance.
