FPR - 944 2.5 8 valve 82-85

Please note,

This particular part is usually installed on the 924S and pre 1986 944 models which have a lock nut on the fuel return fitting around the area where the fuel return hose attaches.

In 1986 this changed to a fuel pressure regulator which had two 10mm bolts clamping it to the fuel rail, where a fitting with an o-ring seals against the fuel rail, these have a push fitting fuel return hose clamped in place with a jubilee clip. 

During 1988 the fuel return hose type on this model changed from being a push on hose, to one secured with a threaded end which screws onto the fuel pressure regulator, instead of being a push fitting.

Please check your car before ordering, even if the date seems correct, it is possible your car may have been modified with a different fitting, if so, check our other fuel pressure regulators, match the part number as printed on your current fuel pressure regulator, or call/email us for assistance in identifying the correct part for your Porsche.

This part is compatible with the following part numbers.

• Evolution - Unlike the original part, this item has benefited from continued improvements. Including having internal components compatible with ethanol fuel, but also having environmentally friendly manufacturing processes, such as not using banned chemicals during the plating process.
• Modern components - This part is ethanol friendly, for use with modern fuels containing ethanol.
• High quality materials - This part is made to a quality level, not down to a price point, including being nickel zinc plated, instead of being just zinc plated like many of the Chinese items on the market.
• Guarantee - This part has a full two year return to base guarantee (As you would get from Porsche).
• Quality control - This part has been tested in the BKlassic fuel lab on a Bosch approved fuel test machine to be within specifications as laid out by Bosch and Porsche.
• Environmental plating - The original Bosch yellow plating process uses chemical processes now outlawed in Europe, this parts major cosmetic difference is not being plated using this process and is a dull silver colour, instead of the yellow plating.
• Standard looking part - Other than using the silver coloured plating process rather than yellow, this part has been designed to look as close to the original Bosch part as possible without breaching patents with Bosch or Porsche, and has been made in a factory which used to make them for Bosch.

• Poor fuel economy (gas mileage or miles per gallon / MPG)
• Loss of performance
• Hesitation
• Misfires
• High exhaust emissions (potentially failing your local roadworthy tests)
• Exhaust smoke

We recommend that if you are suffering from any of these symptoms, that you have your fuel pressure checked by a competent garage, however, fuel pressure regulators do also have a finite lifespan as they contain rubber components which degrade with age. Therefore if your fuel pressure regulator is over 5 years old it may require replacement. If it is over 10 years old, it certainly is in need of replacement.

Important notice.

B-Klassic only develop products in response to a need or gap in the market place.
Due to Bosch discontinuing manufacture of this part, along with the subsequent move by Porsche Classic to buy all available stock from Bosch, B-Klassic found that the only available fuel pressure regulators for the Porsche 924S, 944 and 968 Models were either ones in stock at Porsche, with limited availability at £260 plus local taxes, or very poor quality items originating in China but sold by several companies around the globe hinting at their origins being outside of China (such as Italy for example), which seem to be very poorly made, suffer from incorrect fuel pressure regulation. It is feared that they may leak fuel and become a fire hazard.
We have contacted one major Italian parts brand about the irregularity of their product, and they refused to comment or confirm the parts were made in Europe.

One tell tale sign of the cheap Chinese fuel pressure regulators is the design of where the vacuum hose pushes onto the regulator. A Bosch, Porsche or B-Klassic Part has a swollen area at the end of the fitting, known as a barb, flare or rolled edge to help secure the vacuum hose, the Chinese parts only have a flat cut off tube fitting.

B-Klassic Developed their range of fuel pressure regulators as a high quality alternative to the cheap Chinese parts, with no regard to price, but only to quality, which result in a part which we believe is even better than the original Bosch parts, as sold by Porsche.

Here are some close up views of the correct vacuum hose port design, as found on our B-Klassic fuel pressure regulators.


As you can see, the B-Klassic Part has a correctly formed vacuum port, which is a detail missed by the cheap Chinese copies.
In contrast, in the following photo we have one of the Chinese low cost parts.

Notice how the cheap Chinese part does not have the correctly formed fitting for the vacuum hose to connect to, with no swollen lip to help retain the hose. This is not just a small detail, but the acid test of a quality fuel pressure regulator.
Also notice the Chinese part is plated in yellow plating (more recently a rough silver), which tends to use a process now outlawed in Europe and many countries around the world due to the chemicals involved being harmful to the environment.
