Direct fit replacement for Bosch clip in regulators

Product Details
Takes over where the factory regulator stops
  • Direct fit replacement for Bosch clip in regulators
  • More than double the flow of the factory regulator, allows increased pump capacity without having to replace the factory fuel rail
  • Gasoline, ethanol, and methanol compatible
  • Double layer/double reinforced diaphragms with a burst strength exceeding 1000psi
  • Teflon co-polymer seat with stainless valve to retain fuel pressure longer after shut down
  • Spring pre-load adjustment platform is o-ring sealed and does not leak vacuum/boost
  • Static pressures adjustable from 1.4-5bar (20-72psi – subject to pump flow and factory return line restriction)
  • Completely serviceable
GFB’s popular and compact FX-S Fuel Pressure Regulator is now also available as a direct drop-in replacement for the common Bosch regulators that clip into the fuel rail. If you increase the performance of your engine, you need to ensure your fuel system can deliver the goods or you’re going to have a bad day! Upgrading the fuel pump is the first step, but doing this alone will usually result in excessive fuel pressure, especially at idle. This is because the factory Bosch regulators typically don’t flow enough to support larger fuel pumps, especially with turbo E85 setups that demand high fuel flow rates. Rather than replacing the entire fuel rail, or using an adaptor with a separate fuel pressure regulator, simply clipping in the FX-S 8051 will allow you to run a much larger pump setup even with the factory rail. And if you need to adjust the fuel pressure, that’s no problem - unlike the fixed-pressure Bosch regulators, the FX-S can be adjusted from 1.4bar to 5bar. Like all GFB FX regulators, the FX-S 8051 is compatible with pump gas, Ethanol, or Methanol, and also incorporates a soft Teflon valve seat (rather than metal on metal) that will always positively seal and hold fuel pressure on shut down for reliable engine startups. The double layer diaphragm has twice the reinforcing material of the single layer type used in most regulators, and as a result the burst strength exceeds 1000psi! The 1/8” NPT port can be used for a fuel pressure gauge or electronic pressure sensor, or it can simply be plugged using the port plug provided.

Bosch replacement - replaces rail mounted fuel regulator.

Guarantee / Warranty

GFB Warranty

Built-in Obsolescence? Not with GFB!

We live in a throw-away society, conditioned by cheap products and frequently released new models, to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.

That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it. For full warranty details, please visit the GFB Australia website.

If the fault of occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.

Tech Support: We don't have a "Tech Support" team or department. We have engineers. When you contact us through our tech support email, you will be dealing directly with the engineers who actually design GFB products. They have more experience with the product than anyone on the planet to ensure you get the right advice.

Overseas Customs and Duty Charges

For all customers outside of the UK, the prices on this website will have 20% UK VAT Tax removed at the point of checkout (once you've entered your billing and shipping addresses). However you will likely have to pay some form of Duties / VAT prior to delivery of your goods. You are responsible for paying those charges. Failure to do so will result in the goods being returned to us. As the shipper, we will be charged again by the carrier to return the goods. This amount will be deducted from any refund you may be due.

If you are unsure of the customs and duty charges, we recommend you should contact your local authorities ahead of placing your order.

We do our best to ensure our stock data is accurate on our website. If we're ordering parts to fulfil your order from other manufacturers or suppliers, there can be delays in them despatching goods which may affect the overall delivery time. We will endeavour to do our best to keep you informed if things don't go to plan. We estimate the likely despatch times when you're looking at each part number. If you require parts urgently, please call us on +44 (0)1823 690281 before ordering to confirm availability.

Thank you for purchasing products from Octane Distribution Ltd. We endeavour to offer the best quality products and aftersales care but if you do find yourself in the position where you would like to return goods, we are here to help.

We try our best to ensure correct product/vehicle listings but there are always exceptions to the rule and no cataloguing is 100% accurate.
