Product Overview
Walbro 255LPH Fuel Pump Kit for Toyota Starlet GT Turbo & Glanza V β ITP231A
Give your Toyota Starlet the fuel delivery support it needs with the Walbro 255LPH Fuel Pump Kit (ITP231A). Designed for Toyota Starlet GT Turbo and Glanza V applications, this high-performance in-tank fuel pump upgrade is ideal for enthusiasts building a more capable and reliable fuel system.
Manufactured by TI Automotive, the company behind Walbro’s automotive fuel pump technology, the ITP231A kit uses the established GSS342 high-pressure fuel pump. It is designed for performance applications where increased fuel demand can exceed the capacity of an ageing or standard fuel pump.
Whether you’re refreshing the fuel system on a Toyota Starlet EP82 GT Turbo or upgrading a modified EP91 Glanza V, this Walbro 255LPH fuel pump kit is a practical choice for supporting your engine’s fuelling requirements.
Why Upgrade to a Walbro 255LPH Fuel Pump?
The original fuel pump fitted to an older Toyota Starlet may no longer provide the fuel delivery needed for a modified engine.
As performance upgrades increase airflow and engine load, fuel demand can rise significantly. A suitable fuel pump helps maintain the supply required by the injectors and fuel-pressure system.
The Walbro ITP231A 255LPH in-tank fuel pump kit offers additional fuel-flow capacity for modified Toyota 4E-FTE engines.
It is particularly relevant when upgrading your Starlet with:
- Larger turbochargers
- Increased boost pressure
- Higher-flow fuel injectors
- Performance ECU calibration
- Supporting intercooler and induction upgrades
- Fast-road and track-oriented engine modifications
A higher-capacity fuel pump does not directly increase horsepower. Instead, it supports the fuel delivery required by an appropriately configured engine and fuel system.
Genuine TI Automotive / Walbro GSS342 Pump Technology
At the heart of the ITP231A kit is the Walbro GSS342, a high-pressure electric fuel pump from the established GSS performance range.
The pump is designed for in-tank installation and operates using a 12V electrical supply.
Its compact configuration makes it a popular upgrade for performance vehicles requiring additional fuel delivery without converting to a fully external fuel-pump system.
Key benefits include:
- 255LPH performance pump class: Increased fuel delivery capacity for suitable modified engines.
- GSS342 pump design: Proven high-pressure pump technology.
- In-tank configuration: Designed for installation within the vehicle’s fuel tank.
- 12V electrical operation: Suitable for compatible automotive fuel systems.
- Performance upgrade potential: Supports increased fuel requirements associated with turbocharged engine modifications.
- Application-specific fitting kit: Supplied with installation accessories for the intended Toyota Starlet applications.

Toyota Starlet GT Turbo EP82 Fuel Pump Upgrade
The Toyota Starlet GT Turbo EP82 is a popular platform for Japanese performance tuning.
Powered by the turbocharged 1.3-litre Toyota 4E-FTE engine, the EP82 responds well to carefully selected engine and supporting modifications.
When increasing boost pressure or upgrading the turbocharger, maintaining adequate fuel delivery becomes increasingly important.
The Walbro 255LPH ITP231A kit is marketed for the Starlet GT Turbo and can be considered as part of a properly specified fuel-system upgrade.
Before installation, confirm the existing fuel-pump carrier, electrical connections, fuel-pressure requirements and compatibility with any previous modifications.
Toyota Glanza V EP91 Fuel Pump Upgrade
The Toyota Glanza V EP91 is another popular 4E-FTE-powered performance model.
Many Glanza V owners upgrade their vehicles with aftermarket turbochargers, intercoolers, induction systems and ECU tuning.
These modifications can increase the demand placed on the fuel system.
The Walbro ITP231A fuel pump kit provides an uprated in-tank fuel pump option for compatible EP91 Glanza V applications.

Kit contents should be checked against the supplied manufacturer’s packaging, as installation accessories may vary.
Fuel Flow and Performance
The GSS342 belongs to TI Automotive’s 255LPH performance fuel pump range.
However, actual fuel flow is influenced by operating pressure, supply voltage and fuel-system resistance.
For example, published test data for a GSS342 application records approximately:
- 255 litres per hour at 3 bar
- 225 litres per hour at 5 bar
These are supplier-published test figures, not guaranteed flow rates under every installation condition.
Although the GSS342 is often associated with high-horsepower applications, the exact power it can support depends on engine setup, fuel type, injectors, operating pressure and electrical supply.
Installation and Compatibility
The Walbro ITP231A is intended for compatible Toyota Starlet GT Turbo and Glanza V fuel-tank installations.
Before ordering or installing:
- Confirm the vehicle’s chassis and engine specification.
- Verify the original fuel-pump installation arrangement.
- Check the electrical connections and pump mounting requirements.
- Confirm the fuel pressure and flow required by the engine.
- Arrange professional installation where necessary.
Fuel-system modifications should be carried out using suitable equipment and safe installation procedures.

Frequently Asked Questions
Does the Walbro ITP231A fit the Toyota Starlet GT Turbo?
Yes, ITP231A is marketed as a performance in-tank fuel pump upgrade for the Toyota Starlet GT Turbo. Confirm the individual vehicle’s existing fuel-pump installation before ordering.
Is the ITP231A suitable for the Toyota Glanza V EP91?
The kit is also listed for Toyota Glanza applications, including the turbocharged EP91 Glanza V. Modified vehicles may require additional compatibility checks.
What is the difference between ITP231 and ITP231A?
The ITP231 is associated with the lower-flow GSS250 pump, while ITP231A is associated with the higher-flow GSS342 255LPH pump. They should not be treated as identical products.
Will a Walbro 255LPH fuel pump increase horsepower?
Not directly. A fuel pump provides fuel-flow capacity. Any increase in engine performance depends on suitable engine modifications, ECU calibration and a properly matched fuel system.
Can this fuel pump be used with a larger turbocharger?
It may be suitable for modified turbocharged applications, provided the pump can meet the engine’s fuel requirements at the intended operating pressure.
Is this a universal fuel pump kit?
No. ITP231A is supplied as a vehicle-oriented upgrade kit for particular Toyota applications. The underlying GSS342 pump is used in other vehicles, but the fitting accessories and installation requirements can differ.
