The C6 Z06 Corvette has specific fuel system requirements in order to support the demands of high horsepower turbocharged performance - in a nutshell, huge horsepower demands huge fuel flow that is metered very precisely.

For ultra high horsepower applications as seen on the Z06, APS has developed a thoroughly engineered Extreme Performance Full Return fuel system that is not only very comprehensive, but also highly robust for extereme performance and total peace of mind.

Designed to operate with the APS Intercooled Twin Turbo Z06 System, the heart of the APS Extreme Performance Fuel System is the replacement drop-in surge tank/fuel pump assembly that incorporates twin high volume fuel pumps, return circuit and provision for the stock fuel sender assembly.

Precision construction in stainless steel ensures that the APS drop-in pump assembly delivers bullet-proof reliability and a fume tight seal for total peace of mind.

Each of the twin high volume fuel pumps situated inside the APS drop-in surge tank delivers a huge volume of fuel to their individual Teflon lined stainless steel braided hoses.

By mating each fuel pump with its own fuel line to the engine bay, the maximum flow rate possible is achieved in order to consistently deliver very high fuel flow for high horsepower.

With twin fuel supply lines to the engine bay, each fuel line feeds its own billet aluminium fuel rail, thus eliminating any fuel flow restriction that would have been caused if a single shared fuel supply line was run at such a high horsepower level.

Attention to detail is a signature of APS systems and the APS Twin Pump Fuel Supply System is a perfect example of taking this desirable attribute to new heights. In order to ensure total peace of mind and leak-free operation, the fuel pressure regulator is specified with a DOWTY washer beneath the pressure set screw lock nut and another below the dome nut. This completely eliminates the possibility of even the slightest fuel leakage up the threads of the adjusting screw for zero fuel odor.

In order to deliver rock steady and constant fuel pressure at this high horsepower level, the fuel pressure regulator is boost referenced - which means that the fuel pressure differential across each injector face remains constant regardless of the operational boost pressure level. In other words, consistent fuel pressure is achieved whether decelerating (vacuum), cruise conditions (low boost pressure) right through to very high boost pressure levels commonly experienced at extreme power levels.

Boost pressure referenced fuel pressure also ensures that each of the eight drop-in Quad Orifice 84 lb/min (at 4 Bar fuel pressure) fuel injectors supplied in the APS Extreme fuel system operate to their full potential to deliver and sustain 1,000 horsepower of fuel flow the engine.

The APS Extreme fuel system is a complete bolt-on precision fuel system that consists of a comprehensive range of components designed specifically to support huge horsepower and yet retain excellent fuel atomisation, fuel economy and driveability in day to day driving conditions.

Being a full return fuel system, the APS Extreme Performance fuel system is engineered to return fuel to the APS drop-in surge tank via the stock fuel supply line (the stock fuel supply line now operates as the return fuel line). This takes advantage of the robust single fuel line configuration that has more than sufficient capacity under its new role as a fuel return line.

Each high capacity fuel pump is powered directly through a dedicated custom fuel pump power wiring loom that is supplied with the APS fuel system. This wiring loom is connected via a relay to a high capacity 12V power source. This ensures that the fuel pumps operate at the their absolute optimum and that there is no additional electrical load upon the stock fuel pump electrical circuit.

In addition, highly robust Teflon lined stainless steel braided fuel lines that are spiral wrapped are included with the APS Extreme Performance fuel system for straight forward installation and years of hassle-free high performance motoring.

The APS Extreme Performance Full Return fuel system delivers a huge volume of fuel at a rock steady fuel pressure that is balanced and boost referenced for the ultimate in fuel system performance on extreme horsepower GM LS7 engines.

The APS Extreme Performance fuel system is supplied complete with every nut, bolt, clamp and bracket required for easy installation.
