Raceworks is a range of High Performance AirFuel, and Fluid Management Components.

Raceworks products are manufactured from premium quality materials to ensure the highest specifications and industry standards are surpassed.

Raceworks components include fuel pumps, silicone hoses, fuel rails, aluminium fittings, performance hose, fuel injectors, sensors, connectors and supporting hardware.

Raceworks is available through a network of specialised resellers and leading automotive retail groups who have a passion for performance.

Pro Speed Racing now offer fuel rail packages including quality Raceworks hoses and fittings. This kit can suit any Twin Inlet -6AN Fuel Pressure Regulator including the Turbosmart FPR1200, GFB FX-R and Raceworks FPR-501BK. This kit is designed to suit only aftermarket fuel rails which either have male 6AN male flare fittings already (select No rail fittings) or aftermarket fuel rails which have 8AN female ORB Ports (select rail fittings). Compatible fuel rails include the Radium Engineering.

This kit incorporates the Raceworks 200-Series E85 safe braided hose in either stainless steel braid or black braid. Raceworks 200 Series Teflon Braided Hose is constructed from a PTFE (Teflon) inner tube that is compatible with all fuels, oils, nitrous including brake and clutch fluids. The PTFE (Teflon) tube is covered by a stainless steel outer cover that is durable, and resistant to abrasion and expansion. The Raceworks 200 Series Hose is the best option for use on fuel systems as it won’t allow the permeation of fuel smell, and has the highest pressure and temperature rating in the range of Raceworks hoses.

Raceworks 200/220 Series Hose Ends are all manufactured from 6061 T6 grade billet aluminium. All Raceworks hose ends are hardcoat anodised for maximum protection, and full flow to provide uninhibited fluid movement. Female swivel hose end ensures ease of fitment once 200 Series Hose has been connected. All Raceworks products come with a 2 year warranty.


Fuel Pressure Regulator Options:


If you’re looking for an EFI Fuel Pressure Regulator that seals and behaves just like your factory unit but with the added reliability and high flowing capacity you require, then look no further than the GFB FX range. How have we achieved this? Our engineers have spent countless hours developing a unique replaceable co-polymer valve seat.

What does this mean? Conventional aftermarket performance Fuel Pressure Regulators typically utilize a metal-to-metal valve and seat which by nature will not positively hold pressure when your engine is shut down, which can make startup more difficult.

GFB have incorporated a softer, more compliant yet resilient material for the valve seat, which will always positively seal and hold fuel pressure on shut down, designed to give factory-like sealing and reliable startup, as well as superior fuel resistance suitable for Unleaded, Ethanol, Methanol, and Diesel fuels.

We also use a double layer diaphragm, which means we have twice the reinforcing material, and as a result the burst strength exceeds 1000psi! The multiple inlet/gauge ports also allow for a wide range of fuel system setups beyond the usual inlet/outlet, including parallel fuel rail or returnless “deadhead” systems. The two gauge ports allow you to run a mechanical fuel pressure gauge AND an ECU fuel pressure sensor if you want to.

Turbosmart FPR1200 -

Turbosmart's newest High-performance EFI fuel pressure regulator is smaller, lighter and better! Featuring two -6AN inlet ports, one -6AN return port, and one 1/8 NPT gauge port, 30-90 PSI base pressure adjustment, 1:1 ratio, premium diaphragm and stainless steel valve seat allow for ANY fuel type including E85 and is suitable for engines with up to 1200hp fuel systems. FPR's feature a non-directional bias to regulation, so no matter where the fuel comes in they will regulate the same. Factory tested.

All Turbosmart FPRs are CNC machined in house from billet aluminium stainless steel and hand-assembled and tested to ensure maximum precision. Turbosmart FPR’s have been designed to provide smooth and stable fuel pressure delivery under all conditions from idle to full throttle and are suitable for use with both electric and mechanical fuel pumps. The FPR range features an easy screw and lock adjustment and provide a stable 1:1 ratio between fuel pressure and manifold pressure. Each FPR is backed by a variety of accessories such as fuel rail adapters, gauges and fittings to suit most popular makes and models.

2 x AN-6 Inlets and AN-6 Return. 1/8″ NPT Gauge Port. Base Pressure Range of 40-75PSI (2.75-5.2Bar). Boost Referenced (1:1 Ratio). Boost Reference Port is 1/16″ NPT. Dimensions are 94mm high, 62mm wide and 60mm deep with no fittings. E85 and PUMP Fuel Safe.
