KPM Fuel Systems are proud to release the highest level of direct fit fuel systems for the S550 Mustang GT (2015-2023).

With the modern Mustangs being tuned to amazing power levels comes the need for a high-performance fuel system.

KPM have met this need with a direct replacement high performance fuel system that will perfectly support power levels from standard all the way to 1500 hp.

No other Mustang fuel module supports as much power with the efficiency, functionality, and fuel delivery of the KPM 1500 hp fuel systems.


KPM 1500 HP Fuel Module

The KPM 1500 hp Fuel Module is engineered utilising 2 x high performance Bosch Racing fuel pumps, all housed in an OEM style high-flow fuel canister and distribution manifold. The KPM fuel module is mounted and immersed in the vehicle’s fuel tank as per OEM design and for ease of fitment.

The development and testing of the KPM module was focused on supplying guaranteed delivery of cool, dense fuel to support 1500 hp at the engine on pump fuel. Our objective was also the supply of solid fuel delivery in both everyday road driving and extreme track conditions, regardless of fuel level in the tank

To achieve these objectives, our KPM Fuel System engineer designed and incorporated a four Venturi pump and refill valve system designed to scavenge fuel from both sides of the Mustang fuel tank and permanently keep the fuel canister full.

This means that you can run the KPM fuel module at any fuel level safely across all conditions without the risk of surge or fuel starvation, including during spirited driving, circuit days, or drag racing.

The fuel pumps are 100% petrol, ethanol and methanol compatible and able to deliver massive amounts of cool, dense fuel at standard vehicle voltages.

This equates to optimum tuning and power levels up to 1500 hp (flywheel rated on 98 octane)


KPM Fuel Systems have designed a Pulse Width Modulated (PWM) Fuel Module Controller, that can electronically run the two pumps housed in the KPM 1500 hp Module and also be further upgraded to run the three fuel pumps as housed in the KPM 2200 and four fuel pumps in the KPM 2700 hp Module  .

We have called it the KPM PWM Fuel Module Controller. Its main purpose is to control the supply of fuel flow in accordance with the engine power and fuel demand. It does this by electronically controlling the amount of current supplied to the fuel pumps.

Control of fuel pump current will keep fuel cool and dense preventing vaporisation, retaining maximum energy for optimum power.

The KPM PWM Fuel Module Controller has been designed to be a direct fit addition to all KPM 1500 hp, 2200 hp, and 2700 hp Fuel Systems.

Less fuel pump current = less heat = cooler fuel = more power

Supplying fuel to support 1500 hp and beyond requires two or more high flow fuel pumps, housed in one or more in-tank fuel modules. The drawback to this scenario is that two or more fuel pumps can generate quite a lot of fuel pump current meaning increased heat.
This transfer of heat needs to go somewhere and therefore, heats the fuel in the tank.
This is generally not a concern however, if the vehicle is idling or being driven for long periods with a low level of fuel in the tank, the fuel may start to reach a point of losing its full energy potential or start vaporising in the pumps or fuel lines. This can cause long cranking times and hard re-starts. In the worst cases, the fuel pumps will start to cavitate, lose pressure and not supply fuel as intended.

The KPM PWM controller is pre-programmed to monitor your vehicle fuel pressure across all engine loads which in turn allows the controller to calculate the required level of electrical current to your fuel pumps. This in turn delivers the correct amount of fuel to your engine as required in all conditions.

Cooler fuel means increased performance


Vehicles Factory Fuel System Control Module (FSCM)
S550 Mustang GT (2015-17; & 2018-23)

The Mustang factory fuel system runs one small amperage fuel pump (approx 8-12 amps), therefore the OE Fuel Module Controller FSCM is designed to electronically control only one small amperage fuel pump and no more.

The KPM 1500 hp Fuel System runs two fuel pumps at approx. 16-18 amps each. This is a total of 36-38 amps. You can see that the factory FSCM cannot support the amperage of larger pumps. The KPM PWM Fuel Module Controller is used as a stand-alone controller and bypasses the factory FSCM.

The KPM PWM Fuel Module Controller is supplied with a fuel pressure sensor kit and wiring that directly fits your vehicle’s fuel system. The fuel pressure is then used to calculate the correct current required to run the pumps accordingly.


The KPM 1500 hp Fuel and PWM System is a direct replacement system with the addition of the PWM easily mounted as per the instructions provided. The only extra requirement is to route the high amperage wiring and connector kit, that comes supplied with easy fit OEM style plug and play connectors. Your KPM 1500 hp fuel system is now ready for your tuning professional to calibrate your fuel system and tune your vehicle as normal with any well-known tuning software.
