Impreza WRX STI 08-14

Direct Fit High-Output 300L/H Replacement Ethanol Friendly Fuel Pump

A true ethanol and petroleum friendly replacement fuel pump with flow/pressure capabilities to deliver fuel for up to 280kw at the wheels.

We recommend a Boxer Performance Parts In-Tank Fitting Kit for MY94-MY07 Impreza, WRX, STI, Forester + MY94-MY03 Liberty, Outback.

Note: Our High-Output Fuel Pumps do not have a check valve, therefore slightly longer ‘cranking’ periods are experience before the engine ‘fires-up’, this is a positive side-effect for engine longevity.

The RCM 340 uprated fuel pump kit should be one of the first things you consider installing when modifying your Impreza above stock power levels, as the ability to provide your engine with enough fuel is crucial to performance.

The RCM340 is a high output, in tank, electric fuel pump that directly replaces the standard fuel pump assembly within the fuel tank. With the ability to supply an impressive 340 litres per hour of flow, this kit comfortably out performs other Impreza pumps on the market and is a huge improvement on the standard fuel pumps. 

Ideal for Imprezas developing up to 500bhp and with straight forward fitment via the inspection cover on the cars floor pan, the RCM340 offers superior flow throughout a wide pressure range. With unmatched durability and reliability thanks to its turbine pump mechanism and 30% better performance when compared to its rivals, RCM recommends this pump as a great upgrade for the standard unit or even other popular fuel pump kits on the market.

This pump has also been designed to cope with the New Age Imprezas oscillating voltage supply. Feed to the pump varies from 8v to 12v depending on how the car is being driven.

Supplied with all parts required to fit all turbocharged Impreza models from 2008 + 

• 200LPH @ 90PSI | 6.1 Bar

What's your ethanol percentage?
The ethanol content of E85 fuel can vary from 60% to 92% ethanol. A fill up with E85 can drastically change the mix of fuel in your vehicle.  For performance drivers determining actual ethanol content of E85 is essential to maximizing an engine tune and horsepower.

Why know your ethanol percentage?
E85 has the equivalent octane rating of 105 or higher octane fuel.  Higher octane fuel is more resistant to knock allowing for more aggressive ignition timing, higher compression and increased engine power over gasoline itself. 

The Zeitronix Ethanol Content Analyser helps you get the most out of your engine and fuel.

• Two 0-5 V analog outputs: Ethanol % and Fuel Temperature for use with ECUs, data logging and engine management systems.
• Connecting harness to Zeitronix Flow Through FLEX Fuel Sensor is included. Harness length is 8 ft (2.4m)
• Optional real time E% Ethanol Content Gauge.
  The E%  gauge is only 3/4" (19mm) thick. The back of the gauge is completely flat with cable hidden in a cavity and can besurface mounted almost anywhere inside the car cabin using a piece of Velcro or double sided tape. The E% Gauge base allows the gauge to be mounted in a standard 2” 1/16 (52mm) gauge pod. For additional mounting options the package includes 2 set screws and 2 nuts (4-40 screw size). Check out the gallery for gauge installation pictures.
  The E% Gauge plugs into the ECA-2 GAUGE port. Power and serial data is supplied directly through the single connection - there are no additional +12V or ground wires. The E% Gauge cable length is 5 ft (1.5m).
  ECA-2 is required for E% Gauge operation.
• A flex fuel sensor is required.  The ECA-2 is compatible with some OEM sensors used in GM vehicles with the flex fuel insignia or which run on E85. However GM offers a large number of different sensors with different specs.

• ECA-2 dimensions: 3" x 2" x 1" (76mm x 50mm x 25mm)
• Made in the USA!

What are the sizes of the flex fuel sensor inflow and outflow lines?
Zeitronix Flow Through Flex Fuel Sensor both tubes are 0.37" and 0.5" at the flange.

The usual mounting location for the sensor is the return fuel line.  Make sure the sensor is filled completely with fuel.
A professional installation by a shop familiar with your vehicle and it's fuel system is required. Always check for fuel leaks!

Extreme High-Output Ethanol Friendly Fuel Pump

A true ethanol and petroleum friendly fuel pump with flow/pressure capabilities to deliver fuel for up to 350kw at the wheels.

Note: Modifications to the factory fuel pump carrier bracket or module are required.

Our Extreme High-Output Fuel Pumps do not have a check valve, therefore slightly longer ‘cranking’ periods are experience before the engine ‘fires-up’, this is a positive side-effect for engine longevity.

You can also choose to add a one way check valve if you prefer:
